How many moles of a gas sample are in a
20.0 L container at 373 K and 203 kPa? The gas constant is 8.31 L - kPa/mol -K.

0.33 mole

0.65 mole

1.30 moles

3.05 moles

Sagot :

The moles of the gas sample present is 1.30 , Option C is the right answer.

What is Ideal Gas Equation ?

Ideal Gas Equation states that for an ideal gas , the product of pressure and volume is equal to the product of moles , universal gas constant and the temperature.

PV =nRT

Given in the question

Volume = 20 Litre

T = 373 K

P = 203kPa

R =8.31 L - kPa/mol -K.

Therefore

203 * 20 = n *8.31 *373

n = 1.30 moles

Therefore the moles of the gas sample present is 1.30 .
