I am so confused about what I'm meant to be working out for the analysis of results section etc....
1. Calculate the amount of carbon dioxide collected in the measuring cylinder. Assume that 1 mol of gas occupies 24000 cm^3 at room temp and pressure. (Are you working out mols of volume??)
2. Copper (II) carbonate basic reacts with sulfuric acid as below:
CuCO3.Cu(OH)2 + 2H2SO4 ->2CuSO4 +3H2O +CO2
Deduce the amounts of copper (II) carbonate that reacted.
3. Calculate the percentage by mass of CuCO3 in the original sample of CuCO3.Cu(OH)2.
...And I obtained the results of 126cm^3 and 138cm^3 of CO2 produced in the experiment....
