0.785 moles of N2, fill a balloon at 1.5 atm and 301 K.

What is the volume of the balloon?

V = 12.93 L

Explanation:

Given dа ta:

Number of moles = 0.785 mol

Pressure of balloon = 1.5 atm

Temperature = 301 K

Volume of balloon = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P = Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm. L / mol. K

T = temperature in kelvin

Now we will put the values.

V = nRT/P

V = 0.785 mol * 0.0821 atm. L / mol. K * 301 K / 1.5 atm

V = 19.4 L / 1.5

V = 12.93 L
