Answer:

Number of moles = 2 mol

Explanation:

Given data:

Mass of sulphur dioxide = 128 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of  sulphur dioxide:

Formula = SO₂

Atomic weight of sulfur = 32.065 amu

Atomic mass of oxygen = 16 amu

SO₂ = 32.065 + 16×2 = 64.065 g/mol

Number of moles = 128 g/ 64.065 g/mol

Number of moles = 2 mol
