How many moles of air molecules are within the confines of Express your answer to three significant figures and include the appropriate Hints

Explanation / Answer

According to the ideal gas law , pV = nRT

where p is pressure in atm

V is volume in L = 20.0 L

n is number of moles = 10.0 moles

R is universal gas constant = 0.0821 L.atm/mol.K

T is temperature = 1oC = 274.15 K

So putting all the values we get :

p x 20 = 10 x 0.0821 x 274.15

p = 11.2 atm
