A sample of 1.00 moles of oxygen at 50°C and 98.6 kPa occupies a volume

27.22dm³

Explanation:

Given parameters:

number of moles = 1 mole

temperature = 50°C, in K gives 50+273 = 323K

Pressure = 98.6kpa in atm, gives 0.973atm

Unknown:

Volume of the gas = ?

Solution:

Since the unknown is the volume of gas, applying the ideal gas law will be appropriate in solving this problem.

The ideal gas law is mathematically expressed as;

Pv = nRT

where P is the pressure of the gas

V is the volume

n is the number of moles

R is the gas constant

T is the temperature

Input the parameters and solve for V;

0.973 x V = 1 x 0.082 x 323

V = 27.22dm³
