Question

a gas has a volume of 132.2 liters at 16.7 atm. the final volume is 126.6L, what is the new pressure?

Answer 1

Answer:

17.44atm

Explanations:

According to Boyle's law, the pressure of a given mass of gas is inversely proportional to its volume provided that the temperature is constant. Thiss expressed as:

$\begin{gathered} P\alpha\frac{1}{V} \\ P=\frac{k}{V} \\ k=P_1V_1=P_2V_2 \end{gathered}$

Substitute the given parameters

$\begin{gathered} 132.2\times16.7=126.6P_2 \\ P_2=\frac{132.2\times16.7}{126.6} \\ p_2=\frac{2207.74}{126.6} \\ P_2=17.44atm \end{gathered}$

Hence the new pressure is 17.44atm
