What volume of acetylene gas,C₂H₂,would be required at 0 °C and 1 atm to obtain a 200.0 g C₂H₂ sample? A)4480 L B)1.309 × 10⁵L C)320.0 L D)0.6304 L E)172.1 L

Question

Quizplus · Accepted Answer

The molar mass of C2H2 is 26.04 g/mol. To obtain 200.0 g, you need 200.0 g / 26.04 g/mol = 7.68 mol. At 0 °C and 1 atm, 1 mol of gas occupies 22.4 L. Therefore, 7.68 mol × 22.4 L/mol = 172.1 L.
