The mass in grams of 387 mL of ethylene glycol is 429.57 grams.

<h3>Further explanation </h3>

In Greek letters the density is expressed in letters ρ (read: rho) and is defined as the mass of the substance divided by its volume. The formula that states the relationship between them is

$\boxed{ \ density = \frac{massa}{volum} \ }$

with the symbol as follows

$\boxed{ \ \rho = \frac{m}{V} \ }$

Based on the formula, the standar units of density are kg/m³ or g/cm³.

Objects with identical types will allow the same density. Therefore it can be noted that density is one of the characteristics of a substance because it provides a specified value.

Since we have presented that

volume of ethylene glycol (V) = 387 mL
because 1 mL = 1 cm³ then 387 mL = 387 cm³
density of ethylene glycol (ρ) = 1.11 g/cm³

We need finding the mass (m) in grams of 387 mL ethylene glycol.

The formula can be rearranged to calculate the mass of an object.

$\rho = \frac{m}{V} \rightarrow \boxed{ \ m = \rho \times V \ }$

$Mass = 1.11 \frac{g}{cm^3} \times 387 \ cm^3$

If all other units are crossed out, generating the desired unit is grams, that means the problem is set in the correct dimensions

Mass = 429.57 grams

Hence, the mass of 387 mL ethylene glycol is 429.57 grams.

Note that density is

always constant
can be used as a conversion factor
can be used to identify an unknown hypothetical substance
varies from element to element and substance to substance
can be measured for all substances, solids, liquids, and gases.

How tight or heavy an object can be observed by comparing its density .

Multiply the volume by the density. 1 ml = 1 cm^3

1.11 g/cm^3 * 1 cm^3/mL * 386 mL = 428 g

All your units cancel out except for g which is what you would expect since you want units of mass.

A student has a sample of a solid dissolved in a liquid. The task is to separate the mixture into its pure components. What ques

Lunna [17]

Answer:

When two or more substances, that do not react chemically, are blended together,

the result is a mixture in which each component retains its individual identity and

properties.

The separation of the components of a mixture is a problem frequently encountered

in chemistry. The basis of the separation is the fact that each component has a

different set of physical and chemical properties. The components are pure substances

which are either elements or compounds. Under the same conditions of pressure and

temperature, the properties of every sample of a pure substance are identical. Each

sample melts at the same temperature, boils at the same temperature, has the same

solubility in a given solvent, etc.

Although these and other characteristics can be used to identify a particular

substance, we will be concerned, in this experiment, with the separation of a mixture

into its components, not with the identification of the substances. Techniques used to

separate mixtures rely on differences in the physical properties of the components.

Techniques useful for the separation of mixtures include the following:

DISTILLATION is the purification of a liquid by heating it to its boiling point, causing

vaporization, and then condensing the vapors into the liquid state and collecting the

liquid. Separation of two or more liquids requires that they have different boiling

temperatures. All boiling temperatures can be reduced by decreasing the pressure

on the liquid.

EXTRACTION is the removal of one substance from a mixture because of its

greater solubility in a given solvent.

FILTRATION is the process of removing or "straining" a solid (the chemical term is

precipitate) from a liquid by the use of filter paper or other porous material.

DECANTING is the pouring of a liquid from a solid-liquid mixture, leaving the solid

behind.

CENTRIFUGING is the process of separating a suspended solid from a liquid by

whirling the mixture at high speed.

SUBLIMATION is the physical property of some substances to pass directly from

the solid state to the gaseous state without the appearance of the liquid state. Not

all substances possess this characteristic. If one component of a mixture

sublimates, this property may be used to separate it from the other components of

the mixture. Iodine (I2), naphthalene (C10H8, mothballs), ammonium chloride

(NH4Cl) and dry ice (solid CO2) are some substances which sublime.

CHROMATOGRAPHY is the process of separating a mixture by the distribution of

its components between two phases, one phase being stationary and the other

phase moving. Some examples of chromatography are gas chromatography, paper

chromatography, and thin-layer chromatography.

Which statements describe phase changes? Check all that apply. Particles in a liquid need to move more slowly in order to freeze

Kipish [7]

Answer: Statements (A), and (C) are correct.

Explanation:

The statements that are true are as follows.

Particles in a liquid need to move more slowly in order to freeze.

When a liquid freezes the molecules get attracted towards each other. This attraction of particles occurs slowly. Hence, this statement is true.

Attractive forces between the particles in a liquid are broken when a liquid boils.

When temperature is raised, the molecules in a liquid gains kinetic energy and start to move quickly in random directions. As a result, liquid state changes to gaseous state. Hence, this statement is true.

If the attractive force between gas molecules have to be increased, they should be moving slower instead because moving faster does not help attracting molecules together.

Hence, the statement particles in gas move fast enough to make more attractive forces when the gas condenses is not true.
