Determine the molality and molarity of the solution

Question

At 20 degrees Celsius, An aqueous solution has the 40.00 wt% urea, CH₄N₂O which is having the density of 1.1106 g/mL.

1.Determine the molarity (M) and molality (m) of this solution at 20 degrees Celsius.

2.The density of 40.00%urea solution is 1.1083 g/mL at some other temperature. Determine the molality and molarity of the solution at this temperature.

3. Explain why this new temperature lower or higher than the 20 degrees Celsius?
