Solution: Calculate the volume occupied by 35.2 g of methane gas (CH 4) at 25ºC and 1.0 atm. R = 0.08206 L. atm/mol. Ka) 0.0186 Lb) 4.5 Lc) 11.2 Ld) 48.2 Le) 53.7 L

Solution: Calculate the volume occupied by 35.2 g of methane gas (CH 4) at 25ºC and 1.0 atm. R = 0.08206 L. atm/mol. Ka) 0.0186 Lb) 4.5 Lc) 11.2 Ld) 48.2 Le) 53.7 L

Calculate the volume occupied by 35.2 g of methane gas (CH _{4}) at 25ºC 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

We are asked to find the **volume of methane gas (CH _{4})** at the given conditions. Since mass, temperature, and pressure are given, we will use the

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 CH_{4} is given instead. We’ll** **calculate the moles of CH_{4} using its mass and molar mass.
