The density of a 1 milliter sample of water is 1 gram. express this density in milligrams per liter

sergeinik [125]

The correct answer is 1000 Kg/M³

Density of water =1-g/cm3.

We know 1- g= 10^-³ Kg

cm³ =(10^-2)³= 10^-6

Substituting we get

Density of water

= 1 x (1x10^-³)/10^-6 Kg/M³

= 1x10^3 = 1000 Kg/M³

<h3>what is density?</h3>

Density is the mass of a material substance per unit volume. Density is defined as d = M/V, where d represents density, M is mass, and V is volume. Density is generally measured in grammes per cubic centimetre. Water, for example, has a density of 1 gramme per cubic centimetre, but Earth has a density of 5.51 grammes per cubic centimetre. Density is sometimes measured in kilos per cubic metre (in metre-kilogram-second or SI units). The density of air, for example, is 1.2 kilogrammes per cubic metre. Textbooks and handbooks list the densities of common solids, liquids, and gases.

If a can of soup 150 g mass and 0.75g/ cm^3 density what’s the volume

Liula [17]

Answer:

<h3>The answer is 200 cm³</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density}\\$

From the question

mass = 150 g

density = 0.75 g/cm³

We have

$volume = \frac{150}{0.75} \\$

We have the final answer as

2 The substance has a mass of 0.50 kg.

katen-ka-za [31]

Answer:

68000J/kg

Explanation:

Given parameters:

Mass of the substance = 0.5kg

Quantity of heat transferred to the body = 34000J

Unknown:

Specific latent heat of fusion = ?

Solution:

The specific latent heat is usually involve in phase changes;

H = mL

H is the quantity of heat supplied

m is the mass

L is the specific latent heat

Insert the parameters and solve;

34000 = 0.5 x L

L = $\frac{34000}{0.5}$ = 68000J/kg
