Question 1 Report

If the quantity of oxygen occupying 2.76L container at a pressure of 0.825 atm and 300k is reduced by one-half, what is the pressure exerted by the remaining gas?

1.650atm

0.825atm

0.413atm

0.275atm

Answer Details

Using the combined gas law formula,

Given that P $_{1}$ = 0.825, V $_{1}$ = 2.76 L, V $_{2}$ = 1.38 L, P $_{2}$ = ?

And T1 = T2; we would have P $_{2}$ = [ P $_{1}$ X V $_{1}$ ] / V $_{2}$

: [0.825 X 2.76] / 1.38

= 1.650atm
