The mass of glucose that would be dissolved in 50g of water in order to produce the same lowering of vapour pressure as is produced by dissolving 1g of urea in the same quantity of water is :

Explanation

To solve the problem of finding the mass of glucose that would produce the same lowering of vapor pressure as 1g of urea dissolved in 50g of water, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept**: The lowering of vapor pressure is directly related to the mole fraction of the solute in the solution. According to Raoult's law, the lowering of vapor pressure (ΔP) is proportional to the mole fraction of the solute.

2. **Set Up the Mole Fraction Equation**:
\[
