0.1693 gm of a volatile substance when vapourised displaced 58.9 mL of air measured at `27^@C` and 746 mm pressure. Calculate the molecular mass of the substance. (Aqueous tenstion at `27^@C=26.7mmHg`.)

Text Solution

AI Generated Solution

To calculate the molecular mass of the volatile substance, we can follow these steps: ### Step 1: Calculate the effective pressure (P1) The effective pressure (P1) is calculated by subtracting the aqueous tension from the given pressure. Given: - Pressure (P) = 746 mmHg - Aqueous tension = 26.7 mmHg ...
