I have an assignment that i have to do this weekend and i was wondering if anyone can help me with it, here's the only question that I don't understand;
1)calculate the mass of the water that will react completely with 4.0g of pure calcium metal according to the following equation:
Ca(s) + 2H2O ------ Ca(OH)2(s) + H2(g)
Ar(H) = 1, Ar(O) = 16, Ar(Ca) = 40
I don't know how to convert mole ratio to mass ratio.
