Answer:
The empirical formula of a nonelectrolyte is CH2O. A solution containing 3 g of the compound exerts the same osmotic pressure as that of 0.05 M glucose solution.
Explanation:
Solutions having same osmotic pressure, at a given temperature, have same concentration.
Concentration of compound = concentration of glucose.
6/M×1=0.5
M=6/0.05=120
(CH2O)=12+2+16=30,
n=molecular mass/empirical formula mass.
=>120/30=4
Hence, Molecular formula (CH2O)4=C4H8O4.
