0.05 g of a gas at 750 mm pressure and 25°C occupy a volume of 46.5 mL. Calculate the molecular mass of the gas.

Explanation

To calculate the molecular mass of the gas, we can use the Ideal Gas Law and the concept of molar volume at standard temperature and pressure (STP). Here’s a step-by-step solution:

### Step 1: Convert the given temperature to Kelvin
The temperature is given as 25°C. To convert this to Kelvin, we use the formula:
\[ T(K) = T(°C) + 273.15 \]
\[
