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

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(1)/(V) \\ P=(k)/(V) \\ k=P_1V_1=P_2V_2 \end{gathered}`

Substitute the given parameters

`\begin{gathered} 132.2*16.7=126.6P_2 \\ P_2=(132.2*16.7)/(126.6) \\ p_2=(2207.74)/(126.6) \\ P_2=17.44atm \end{gathered}`

Hence the new pressure is 17.44atm
