How many milliters of 1.80M HCl are required to react with 30.0 grams of calcium hydroxide according to the given equation:

CA(OH)2(s) + 2HCl(aq)> CaCl2(aq) + 2H2O(l)

1 answer

moles Ca(OH)2 = M x L = ??
Using the coefficients in the balanced equation, convert moles Ca(OH)2 to moles HCl. (It will be 2 x moles Ca(OH)2).
Then M HCl = moles HCl/L HCl
Solve for L HCl and convert to mL.
