Acetylene gas is produced from calcium carbide and water.If 32 g of calcium carbide is consumed, how many g?

g water are needed? Thank you everyone .....

The balanced reaction is: CaC2 + 2H2O ---> C2H2 + Ca (OH) 2 Molar mass of CaC2 is 64 g / mol if you start with 0.5 moles of calcium carbide. For the reactions of water with CaC2 is a ratio of 1:2, you'll need twice as much water, or 1.0 moles of water = 18 grams of water.
