Here's a precise problem for a chemistry student to solve:A gas, initially at a pressure of 1 atm and a temperature of 20°C, is contained in a cylinder with a volume of 5 L. If the gas is allowed to expand to a volume of 10 L at a constant temperature of 20°C, what is the final pressure of the gas? Use the ideal gas law equation to solve the problem.

A chemistry student needs to determine the percentage of calcium carbonate (CaCO3) present in a mixture of calcium carbonate and calcium phosphate. The student has the following information: A 1.00-gram sample of the mixture was dissolved and reacted with excess hydrochloric acid (HCl), producing 0.236 grams of carbon dioxide (CO2) gas. The balanced chemical equation for the reaction is: CaCO3 + 2HCl → CaCl2 + CO2 + H2O. The student also knows that the molecular weight of CaCO3 is 100.09 g/mol and that of Ca3(PO4)2 is 310.18 g/mol. What is the percentage of calcium carbonate in the mixture?
