Calculate these volumes.
(a) what is the volume of 25 g iodine, density =493 g/cm3
(b)What is the volume of 3.28 g gasoous hydrogen, density =0.089 g/L?

A) mass / volume = density
25g/v = 493g/cm3
25g = 493g/cm3 • v
25g / 493g/cm3 = v
0.051cm3 = v

B) mass / volume = density
3.28g / v = 0.089g/L
3.28g = 0.089g/L • v
3.28g / 0.089g/L = v
37 L = v

25 grams of iodine is given to have the volume of 0.051cm³. The volume of 3.28 grams gaseous hydrogen is 37 L.

What is density?

Density is given as the mass of the sample per unit volume. It can be expressed as:

Density = Mass/Volume

  • The volume of 25 grams of Iodine having density of 493g/cm³ is:

493g/cm³ = 25 g/Volume

Volume = 25 g/ 493g/cm³

Volume = 0.051cm³

Thus, 25 grams of iodine is given to have the volume of 0.051cm³.

  • The volume of gaseous hydrogen with mass 3.28 g having the density of 0.089 g/L is:

0.089 g/L = 3.28 g/ Volume

Volume = 3.28 g/ 0.089 g/L

Volume = 37 L

Thus, the volume of 3.28 grams gaseous hydrogen is 37 L.
