CaC2 + 2 H2O -------------> C2H2 + Ca(OH)2
Since the equation indicates a 1:1 mole ration, the moles of acetylene are 5.05.

stoichiometry;you've already got a balanced equation, so multiply the 5.50 moles of CaC2 by potential of (a million mole C2H2/1mole CaC2); moles CaC2 will cancel out, leaving moles of C2H2. the added water basically signifies that there is adequate water for the reaction to ensue. the single mole of CaC2 and a million mole C2H2 are the coefficients of both CaC2 and C2H2.
