Chemistry HW, help?!?
1) Carbonates react with acids to form a salt, water and carbon dioxide gas. When 59.1 g of calcium carbonate are reacted with sufficient hydrochloric acid, how many grams of calcium chloride will be produced?
2) Write a balanced equation for the fermentation of glucose, C6H12O6, into ethyl alcohol, C2H5OH and CO2.
(Write in all coefficients, even if it's 1.)
C6H12O6 -> C2H5OH + CO2
Determine how many liters of ethyl alcohol (d= 0.789 g/mol) can be produced from 575 lb of glucose.

1)
CaCO3 + 2 HCl → CaCl2 + H2O + CO2
(59.1 g CaCO3) / (100.0875 g CaCO3/mol) x (1 mol CaCl2 / 1 mol CaCO3) x (110.9840 g CaCl2/mol) =
65.5 g CaCl2
2)
1 C6H12O6 → 2 C2H5OH + 2 CO2
"0.789 g/mol" is very unlikely, so supposing you meant "0.789 g/mL":
(575 lb C6H12O6) x (453.592 g/lb) / (180.1559 g C6H12O6/mol) x (2 mol C2H5OH / 1 mol C6H12O6) x (46.0684 g C2H5OH/mol) / (0.789 g/mL) = 169060 mL = 169 L C2H5OH
