Question

Given that the density of Hg at 0°C is about 14 g/ml, which of the following is closest to the volume of one mole of Hg?

a. 1.4 mL
b. 14 mL
c. 140 mL
d. 1400 mL

Answer 1

The volume of one mole of Hg is closest to 14 mL.

Step-by-step explanation:

The density of Hg at 0°C is about 14 g/mL. To find the volume of one mole of Hg, we can use the molar mass of Hg, which is 200.59 g/mol. The volume can be calculated by dividing the mass by the density:

Volume = Mass / Density = (1 mol Hg)(200.59 g/mol) / (14 g/mL) = 14.33 mL/mol.

Therefore, the closest volume to one mole of Hg is 14 mL (option b).
