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