well first of all you should balance out the equation first
Ca + 2 HF = CaF2 + H2
ok now find out the ratio of base to acid
which would be 1:2
Could you tell me the answer?

what do you mean?
The answer, so I can be sure of my solution.
i dont have it its not MC
H2 = 2. 12.4/2 = 6.2 What's the atomic weight of calcium? AWC * 6.2 * 1/2 * 1/1.55. But I am not really sure of my answer. Never been strong at chemistry :/
AWC for Atomic Weight Calcium.
