Question

500 mL of nitrogen at 0.900 bar pressure and

1000 mL oxygen at 0.80 bar pressure are put

together in a 2 L flask. If temperature is kept

constant, calculate the final pressure of the

mixture.​

Answer 1

Answer:

0.634 bar

Explanation:

PN2 x 2000ml = 0.93 bar x 500 ml

PN2 = 0.234 bar

PO2 x 2000ml = 0.8 bar x 1000 ml

PO2 = 0.4 bar

therefore the final pressure of the mixture is

PN2 + PO2

0.234 + 0.4 bar

0.634 Ans .
