Solution

The correct option is C
Mass of glucose = 125g, Mass of water = 375g

Given mass of solution (M) = 500g

Concentration of solution = 25%

Since, Mass by Mass percentage of solution = [Mass of solute (m)/Mass of solution (M)] $\times$ 100
$\Rightarrow$ 25 = $\frac{m}{500} \times 100$

$\Rightarrow$ m = $\frac{25}{100} \times 500$ = 125g

$\Rightarrow$ Mass of solute = 125 g

Mass of solvent (water) = M - m = 500g - 125g = 375 g
