Franco Werner · Answer 1

T = 0.38 K

Explanation:

Given dа ta:

Number of moles = 4.75 mol

Pressure = 1.2 atm

Volume = 0.125 L

R = 0.0821 atm. L / mol. K

Temperature = ?

Solution:

Formula:

PV = nRT

T = PV/nR

T = 1.2 atm * 0.125 L / 4.75 mol * 0.0821 atm. L / mol. K

T = 0.15 / 0.39 / K

T = 0.38 K
