What is the mass of 4.700 mol Ca(OH)2? Answer in units of g.

I got .06343g but it's wrong?
Answered by oobleck
since the molar mass of H alone is 1, 4.700 moles of H will be 4.700 grams
I think maybe you got the number of moles in 4.700 grams.

moles * grams/mole = grams
Answered by DrBob222
grams = mols x molar mass
grams = 4.700 x about 74 = ?
Ca(OH)2 = about 40 + 2*16 + 2*1 = about 74
