produced?
CaC2 (s) + 2H2O (l) ----> Ca(OH)2 (aq) + C2H2 (g)
How do i go about solving this?

well ther's a great formula our teacher gave for this one:
moles over coefficient = moles over coefficient.
5.50 mol CaC2 / 1 = X mol C2H2 / 1
5.50=X

stoichiometry;you already have a balanced equation, so multiply the 5.50 moles of CaC2 by (1 mole C2H2/1mole CaC2); moles CaC2 will cancel out, leaving moles of C2H2. The excess water just means that there is enough water for the reaction to take place.
The one mole of CaC2 and 1 mole C2H2 are the coefficients of both CaC2 and C2H2.

I may be mistaken, but since one molecule of CaC2 reacts to form one molecule of C2H2, and a mole consists of 6.022 x 10^23 molecules (Avagadro's number), there should be the same amount of C2H2 in moles as CaC2 moles because it reacts in a 1:1 ratio, assuming a perfect reaction. Hope this helps. Therefore, 5.5 moles of CaC2 should make 5.5 moles of C2H2. Hope this helps.
