Answer:
The answer to your question is 0.32 moles of water are needed.
Explanation:
Data
mass of CaC₂ = 10 g
mass of water = ?
Process
1.- Write the balanced reaction
CaC₂ + 2H₂O ⇒ C₂H₂ + Ca(OH)₂
Reactant Element Product
1 Ca 1
2 C 2
4 H 4
2 O 2
The reaction is balanced
2.- Convert mass of CaC₂ to moles
molecular mass CaC₂ = 40 + (2 x 12)
= 40 + 24
= 64 g
64 g of CaC₂ ----------------- 1 mol
10 g ----------------- x
x = (10 x 1) / 64
x = 10/64
x = 0.16 moles of CaC₂
3.- Calculate the moles of water
1 mol of CaC₂ ----------------- 2 moles of water
0.16 moles of CaC₂ --------- x
x = (0.16 x 2) / 1
x = 0.32 moles of water
