To calculate the molar mass of the gas collected over water, we will follow these steps: ### Step 1: Calculate the pressure of the gas The total pressure of the gas collected is given as 0.993 bar, and the aqueous tension (pressure of water vapor) at 25°C is 0.0317 bar. The pressure of the gas can be calculated using the formula: \[ P_{\text{gas}} = P_{\text{total}} - P_{\text{water}} \] Substituting the values: ...
