Approximate temperature of a. 7 mold sample of a gas at 1.2 ATM and volume of. 170 L

Assuming you meant a 0.7 mole sample of a gas, we can approximate this by assuming that the gas is acting ideally, and use the ideal gas law PV=nRT. Using the following values:

P = 1.2 Atm

V = 0.170 L

n = 0.7 mol

R = 0.08206 L-atm/mol-K

We can rewrite the equation as: PV/nR = T

Plug in our values:

(1.2 atm) (0.170 L) / (0.08206*0.7 moles) = approximately 3.55 Kelvin = T
