A mixture of C3H8 and C2H2 has a mass of 2.9g. It is burned in excess O2 to form a mixture of water and carbon dioxide that contains 1.4 times as many moles of CO2 as of water. Find the mass of C2H2 in the original mixture. If possible, could I get a step by step solution for the problem?

n this exercise, weighed samples of a solid unknown containing NaCl and NaHCO3 react with hydrochloric acid. The volume of the CO2 liberated by the reaction in the gas phase is measured with a gas collection syringe. From the volume we can calculate the number of moles of CO2 in the gas phase using the ideal gas approximation. Since the CO2 is generated in an aqueous environment (aqueous HCl), some CO2 will dissolve in the liquid phase. The amount of...
