Figure 2 shows the volume of gas produced when a Group 2 metal carbonate is heated. Figure 2

The student collected 5.2 dm3 of gas.
What mass of the Group 2 metal carbonate is heated?
Mass = g
(1)

(f) Calculate the mass of the Group 2 carbonate needed to produce 24 dm3 of gas.
Use your answer from part (e) to help you.
