What is the mass of 0.921 moles of sulfur dioxide gas

mass = 58.944 g

given data:

number of moles of SO₂ = 0.921 mol

mass of SO₂ = ?

solution:

formula:

number of moles = mass/ molar mass

- first of all we will calculate the molar mass.

SO₂ = 32 + 16×2 = 64 g/mol

- now we will put the values in formula.

- number of moles = mass/ molar mass

0.921 mol = mass /64 g/mol

mass = 0.921 mol × 64 g/mol

mass = 58.944 g

that tool would be a compass
