STP is abbreviation for Standard Temperature and Pressure at which the temperature is 273 K and pressure is 1 atm

- At these conditions the molar volume is equal to 22.4 L

so 1 mole of SO₂ volume = 22.4 L

? mole of SO₂ volume = 2.5 L

number of moles = 2.5 / 22.4 = 0.1116 mol

mass of SO₂ = 0.1116 * 64.063 = 7.15 g
