Question
36. Acetylene (C,H,) can be manufactured by the reaction
of water and calcium carbide, CaC:
CaC,(s) + 2 H,O(l)
C,H,(g) + Ca(OH);(aq)
When 44.5 g of commercial grade (impure) calcium car-
bide is reacted, 0.540 mol of C,H, is produced. Assum-
ing that all of the CaC, was reacted to C,H2, what is the
percent of CaC, in the commercial grade material?
