Given :
The pressure of 50.0 mL of oxygen gas at 100 ºC increases from 735 mm Hg to 925 mm Hg.
Temperature remains constant.
To Find :
The final volume.
Solution :
735 mm Hg = 0.967 atm
935 mm Hg = 1.230 atm
We know, at constant temperature :
![P_iV_i=P_fV_f\\\\V_f=(P_iV_i)/(P_f)\\\\V_f=(0.967* 50)/(1.230)\\\\V_f=39.31 \ mL](https://img.qammunity.org/2021/formulas/chemistry/college/vgl9lq4b3wy2dwu9gvdlfyqthg1k6vw69v.png)
Therefore, final volume is 39.31 ml.
Hence, this is the required solution.
