Calculate the mass of ascorbic acid `(` Vitamin `C,C_(6)H_(8)O_(6))` to be dissolved in `75g` of acetic acid to lower its melting point by `1.5^(@)C. K_(f)=3.9 K kg mol ^(-1)`

Explanation

To solve the problem of calculating the mass of ascorbic acid (Vitamin C, C₆H₈O₆) to be dissolved in 75 g of acetic acid to lower its melting point by 1.5 °C, we will use the formula for freezing point depression:

\[ \Delta T_f = K_f \times m \]

Where:
- \(\Delta T_f\) = change in freezing point (melting point)
