Question

The boiling point of water at 735 torr is 99.07°C.The mass of NaCl added in 100 g water to make its boiling point 100°C is ( K_b = 0.51 K kg mol^-1)

ans: 5.34 g

Solution

Look at the step before. The units are in kg. Inorder to convert it into 100g water.
We multiply by 100/1000 ie 1/10.
Always check the units
