Question

What is the molality of a solution that contains 31.0 g HCl in 5.00 kg water? (molar mass of

HCI = 36.46 g/mol)

Answer 1

0.17M

Step-by-step explanation:

5kg of water contains 5 liters as the density of water is 1000
`kgm^(-3)`

Therefore one liter of water contains 31/5=6.2g of HCl

Molality of the solution = 6.2/36.46 =0.17M
