{ 25. Calcium carbonate decomposed upon heating to give calcium oxide and carbon dioxide. A sample of
calcium carbonate is decomposed and the carbon dioxide is collected in a 250.0-ml flask. After the
decomposition is completed, the gas has a pressure of 1.3 atm at a temperature of 31°C. How many
moles of CO2 gas were generated? (0.013 mol)
26. Compute the relative rate of diffusion of argon to helium. (3.16)
