How Many Atoms Of Oxygen Are In 2.50 Moles Of So2?

2.50 moles of SO2 has a mass of 44.02 g and the formula is SO2. The density of SO2 is 2.45 g/cm^3.

The molar mass of SO2 is 106.96 g/mol, so there are 2.50 mol in 44.02 g or 0.49 mol in 1 gram of SO2.

The molar mass of O2 is 32 g/mol, so there are 2.50 mol in 44 g or 0.55 mol in 1 gram of O2.

There are 2 x 0.55 = 1 mole of O2 in 1 mole of SO2, so there are 2 x 0.49 = 0.98 moles of O2 in 0.98 moles of SO2 (ie the same number).
