4.375 g of a substance when dissolved in...

`4.375 g` of a substance when dissolved in `36.0 g` of water, lowered its vapour pressure by `0.5 mm` at a given temperature. The vapour pressure of water at this temperature is `25.0 mm`. Calculate the molecular weight of solute.

Text Solution

AI Generated Solution

To calculate the molecular weight of the solute, we can follow these steps: ### Step 1: Understand the given data - Mass of solute (substance) = 4.375 g - Mass of solvent (water) = 36.0 g - Lowering of vapor pressure (ΔP) = 0.5 mm - Vapor pressure of pure water (P₀) = 25.0 mm ...
