Answer:
30.0g/mol
Explanation:
Step 1: Given data
- Mass of the gas: 0.125 g
- Pressure (P): 1 atm (standard pressure)
- Temperature (T): 273.15 K (standard temperature)
- Volume (V): 93.3 mL
Step 2: Calculate the moles of the gas
We will use the ideal gas equation.
Step 3: Calculate the molar mass of the gas
4.16 × 10⁻³ moles correspond to a mass of 0.125 g. The molar mass of the gas is:
