# A 500 mL sample of oxygen gas at 760 mmHg is compressed to 100 mL. What is the new pressure?

Dec 13, 2016

Approx. $5 \cdot a t m$.......

#### Explanation:

Given constant temperature and a constant quantity of gas,

${P}_{1} {V}_{1} = {P}_{2} {V}_{2}$.

And thus P_2=(P_1V_1)/V_2=(1*atmxx500*mL)/(100*mL)=??atm.

Note that you would never quote a pressure OVER $1 \cdot a t m$ in $m m$ $H g$.
