The correct answer is 0.609 m.

the formula is C1.V1 =C2.V2

the equation 5.9(62mL) =C (600.mL)

C= 0.609 m

The concentration of a solution can be used to determine how much solute has been dissolved in a given volume of solvent or solution. A concentrated solution is one that has a large concentration of dissolved solute. If there is only a small amount of dissolved solute in a solution, it is said to be dilute. Solutions Concentrations There are three ways to measure molality: molarity, molality, and mole fraction. The concentration of the solute in the solution is diluted when a solvent is introduced. Concentration increases the solute concentration in the solution by eliminating the solvent. Find the concentration of the solution after dilution using the equation c2 = (c1V1)/V.

Rank the states of matter from the LEAST amount of energy to MOST
nataly862011 [7]

Answer:

The ranking of matter from the LEAST amount of energy to MOST amount of energy is;

B. Solid, Liquid, Gas

Explanation:

The kinetic energy of the particles that make of matter depends on the temperature of the particles and the particles are constantly vibrating

Solid state (Least amount of energy)

In the solid state, the matter is held in solid (rigid) crystal lattice and the particles are rigidly located next to other adjacent particles and stacked up layer by layer

Liquid state (Intermediate amount of energy)

As the temperature of the particles are increased by heating, the particles (atoms and molecules) gain more kinetic energy and their vibration is increased which on further heating, leads to the breaking of the lattice bond of the solid state and the particles are then readjusted to exist side by side rather than being stacked on one another and the assume the liquid state

Upon further heating the particles in the liquid acquire more energy and are  and rather than exist side-by-side, they are able to exist as individual particles in the gaseous form

Gaseous state (Most amount of energy)

From the kinetic theory of matter, the molecules of matter in the gaseous state contains enough energy which is more than the intermolecular forces of attraction such that the particles are able to move and occupy the entire volume of the container in which it is placed

Therefore, the correct option is Solid, Liquid, Gas.

6) Given that the density of olive oil is 0.92 g/mL, calculate the followin a. The mass of 20.0 mL of olive oil. The volume of 2
fgiga [73]

<u>We are given:</u>

Density of Olive oil = 0.92 g / mL

<u>Mass of 20 mL Olive oil:</u>

We know that the density = 0.92 grams / mL

multiplying the numerator and the denominator by 20

Density = 0.92 * 20 grams / 20 mL

Density = 18.4 grams / 20 mL

So, we have 18.5 grams in 20 mL of Olive oil

<u>Volume of 20 grams Olive oil:</u>

We need to multiply the numerator and the denominator of density by a number, that when multiplied by 0.92 will give 20

<em>let that number be x:</em>

<em>0.92 * x = 20</em>

<em>x = 20/0.92</em>

<em>x = 21.74 (approx)</em>

<em />

Multiplying the numerator and the denominator by x:

Density = 0.92 grams / 1 mL

Density = 0.092 * 21.74 / 21.74 mL

Density = 20 grams / 21.74 mL

So, we can see that 20 grams of the oil will have the volume 21.74 mL

An exploratory robot was sent to the planet mars. The gravity on mars is weaker than the gravity on earth. Compared to the mass
Semmy [17]

Answer: An object has a weight of 10 kg on the surface of Earth. If the same object were transported to the surface of Mars, the object would have a weight of 3.8 kg. The density of the object is greater on Earth than it is on Mars.
