Marking points
A1 · 1 mark · Completes volume of nitrogen as 2.2 dm³.
A2 · 1 mark · Completes volume of helium as 1500 cm³.
A3 · 1 mark · Completes volume of chlorine as 1.4 dm³.
Worked solution
Nitrogen: 2200 cm³ ÷ 1000 = 2.2 dm³
Helium: 1.5 dm³ × 1000 = 1500 cm³
Chlorine: 1400 cm³ ÷ 1000 = 1.4 dm³
