Question

Using stoichiometry, solve a and b using the following balanced equation:

CaC2 + 2 H2O -> C2H2 + Ca(OH)2

a. How many grams of acetylene (C2H2) are produced by adding excess water to 5.00g CaC2?

b. How many moles of CaC2 are needed to react completely with 1.92x10^24 moles of H2O?

Thanks )

Answer 1

a.2.0 grams of acetylene (C2H2) are produced by adding water to 5.0 grams of CaC2.

I'm sorry i don't the answer for the other one
