CaC2(s) + 2H2O(l) ---------------> Ca(OH)2 + C2H2
moles of CaC2 = 100/64 therfore moles of actelyne is also = 100/64.
moles of CaC2 = 100/64 therfore moles of actelyne is also = 100/64.
Volume at NTP would be = moles of acetylene * 22.4 hence.

CaC2+2H2o ---Ca(OH)2+C2H2. Means 1mole of cac2 gives 1mole of acetylene or 22.4 lit of gasNow 64g of CaC2 gives 22.4 lit. So 100g of CaC2 gives 22.4* 100/64 = 35 lit of gas ( here * used for multiplication
