R = 0.08208 L·atm/mol·K (based on data given)

Explanation:

PV = nRT = > R = PV/nT

P = Pressure in atmospheres = 3.00 atm

V = Volume in Liters = 17.4 Liters

n = moles of substance = 2.00 moles

T = temperature in Kelvin = 45°C + 273 = 318K

R = (3.00atm) (17.4L) / (2.00mol) (318K) = 0.08208 L·atm/mol·K
