please answer fully for a great review :)

What mass (in grams) of Ag2SO4 contains 4.821023 molecules? Iron reacts with chlorine according to the following reaction: 2Fe+3Cl22FeCl3 How many moles of chlorine would be needed to completely react with 30 . moles of iron? Question 13 5 pts Propane undergoes combustion according to the reaction: C3H8+5O23CO2+4H2 If 427.0g of C3H8 are burned with excess oxygen, what mass (in grams) of carbon dioxide will result? Ammonia is produced according to the reaction: 3H2+N22NH3 If 15.95g of H2 react with 40.17g of N2, what mass (in grams) of ammonia can be produced? Question 15 As the size of the carbon chain increases, combustion reactions can become a bit more complicated to balance. Hexane undergoes combustion according to the reaction: 2C6H14+19O212CO2+14H2O If 113.73g of hexane (C6H14) reacts with 330.67g of O2, what mass (in grams) of water should result? Question 16 7 pts Calcium chloride and sodium phosphate react according to the following balanced chemical equation: 3CaCl2+2Na3PO4Ca3(PO4)2+6NaCl If 507.5g of CaCl2 react with 507.5g of Na3PO4, what mass (in grams) of excess reactant will remain once the reaction is complete? If an experiment is expected to produce 84.6g of product, but experimentally only gives 78.9g. what is the percent yield of this reaction?
