What is the mass of 0.600 mol of ozone molecules, O3? Use O = 16.00 g/mol.
A9.60 g
B19.2 g
C28.8 g
D14.4 g
Answer & Solution
Correct answer: C. 28.8 g
1. One mole of O3 has a molar mass of 3 x 16.00 = 48.00 g/mol.
2. Mass equals moles times molar mass: 0.600 mol x 48.00 g/mol.
3. The product is 28.8 g of ozone.
4. The value 9.60 g treats the sample as single oxygen atoms, and 19.2 g treats it as O2.
