A1.00 l volume of hcl reacted completely with 2.00 l of 1.50 m ca(oh)2 according to the balanced chemical equation below. 2hcl + ca(oh)2 mc013-1.jpg cacl2 + 2h2o what was the molarity of the hcl solution?

Given the balanced chemical equation:

2HCl + Ca(OH)2 ---> CaCl2 + 2H2O

Vhcl = 1 L
Vcaoh2 = 2 L
Ccaoh2 = 1.5mol/L

To solve for the concentration of HCl:

Chcl = ((1.5mol/L * 2L) * (2mol HCl/1 mol Ca(OH)2)) / 1L
        = 6 mol/L
