🤓 Based on our data, we think this question is relevant for Professor N/A's class at Ryerson University.
We are asked to find the volume of methane gas (CH4) at the given conditions. Since mass, temperature, and pressure are given, we will use the ideal gas equation to calculate for the volume.
P = pressure, atm
V = volume, L
n = moles, mol
R = gas constant = 0.08206 (L·atm)/(mol·K)
T = temperature, K
In the ideal gas equation, moles are needed but the mass of CH4 is given instead. We’ll calculate the moles of CH4 using its mass and molar mass.
Calculate the volume occupied by 35.2 g of methane gas (CH4) at 25 °C and 1.0 atm. R = 0.08206 L•atm/mol•K
a) 0.0186 L
b) 4.5 L
c) 11.2 L
d) 48.2 L
e) 53.7 L
