# A sample of gas has a volume of 2.4 L and a pressure of 1.2 atm. What would the pressure of the same gas sample be if the volume is reduced to 1.8 L at a constant pressure?

$\text{New volume } =$ $1.6 \cdot L$
${P}_{1} {V}_{1} = {P}_{2} {V}_{2}$, amount of gas, and temperature constant.
${P}_{2} = \frac{{P}_{1} {V}_{1}}{V} _ 2$ $=$ $\frac{1.2 \cdot a t m \times 2.4 \cdot L}{1.8 \cdot L}$
