AI Generated Solution

To calculate the molecular mass of the gas, we will follow these steps: ### Step 1: Understand the conditions at STP At Standard Temperature and Pressure (STP), 1 mole of any ideal gas occupies a volume of 22.4 liters (or 22,400 mL). ### Step 2: Convert the volume of the gas from mL to liters The given volume of the gas is 94.5 mL. To convert this to liters: \[ ...
