Noe Dougherty · Answer 1

n = 0.52 mol

Explanation:

Given dа ta:

Volume of tire = 1.45 L

Temperature = 28 °C (28+273 = 301 K)

Pressure of gas = 8.80 atm

Moles of gas present = ?

Solution:

Formula:

PV = nRT

P = Pressure

V = volume

n = number of moles

R = ideal gas constant

T = temperature

Now we will put the values:

Ideal gas constant = R = 0.021 atm. L/mol. K

8.80 atm * 1.45 L = n * 0.0821 atm. L/mol. K * 301 K

12.76 atm. L = n * 24.7 atm. L/mol

12.76 atm. L / 24.7 atm. L/mol = n

n = 0.52 mol
