You calculate the density of a substance by dividing its mass by its volume.

Density = mass/volume

For example, if a rock has a mass of 45 g and a volume of 15 cm^3, its density is

Density = 45 g/15 cm^3 = <em>3.0 g/cm^3 </em>

A sample of metal has a mass of 21.35 g, and a volume of 6.28 mL. What is the density of this metal?

Scilla [17]

Answer:

3.40g/mL

Explanation:

Density is a measure of mass over volume, so to get the density all we have to do is divide the mass by the volume.

21.35g ÷ 6.28 mL = 3.40g/mL

The equilibrium shifts to the side having the lesser volume or number of moles

Explanation:

Reaction 2N₂ $g_{123}$ + 3H₂ $g_{123}$ ⇄ 2NH₃ $g_{123}$

This reaction, haber process is completely a combination of gaseous molecules.

An increase in pressure will shift the equilibrium position to the right hand side i.e the side with the lesser volume or number of moles.
