Molarity = moles of solute / volume of solution in Liters. 5.00-kg of water has a volume of about 5.00-L so M = 31-g HCl / (36.5-g/mol x 5.00-L) = 0.170-mol/L

The density of water is 1g/mL
5.00kg = 5000g
Therefore we have 5000mL
5000mL = 5L
Molecular mass of HCl = 36.45g/mol
31.0g / 36.45g/mol = 0.85048moles of HCl
Molarity = moles / Liters
xM = 0.85048moles / 5L
x = 0.17M
