How many grams of CaO (56.08) are required for complete reaction with HCl (36.46) in 275 mL of a 5.90 M HCl solution? CaO + 2HCl --> CaCl2 + H2O.
Answered by DrBob222
mols HCl = M x L = 5.90M x 0.275L = ?
Look at the coefficients in the balanced equation to find mols CaO = mols HCl x 1/2.
Then g CaO = mols CaO x molar mass CaO
