Determine the mass in grams of each of the following:

(a) 0.600 mol of oxygen atoms

(b) 0.600 mol of oxygen molecules, O2

(c) 0.60 mol of ozone molecules, O3

A) 9.60 g

B) 19.2 g

C) 28.8 g

Explanation:

A) Elemental oxygen mass is 16.00 g/mol, so in 0.600 mol of elementar oxygen there is 9.60 g

0.600 mol x 16.00 g/mol=9.60 g

B) Oxygen molecular mass is 32.00 g/mol, so in 0.600 mol of oxygen molecules there is 19.2 g

0.600 mol x 32.00 g/mol=19.2 g

C) Ozone molecular mass is 48.00 g/mol, so in 0.600 mol of oxygen molecules there is 28.8 g

0.600 mol x 48.00 g/mol=28.8 g
