Use the ideal gas law to calculate the volume of a gas in liters (L) that has 1.4 moles at 1.9 atm pressure and 48oC. Input your numerical answer only without units.

Volume = 19 L

Step-by-step explanation

Formula:

PV = nRT

where:

P = pressure (atm)

V = volume (L)

n = no. of moles (mol)

R = gas constant (0.08206 L atm/mol K)

T = temperature (K)

Solution:

PV = nRT

(1.9 atm)(V) = (1.4 moles)(0.08206 L atm/mol K)(48^oC + 273.15)K

V = 19.41 L 

Since the given values have only 2 significant figures:

V = 19 L
