If the pressure of a 2.00 L sample of gas is 50.0 kPa, what pressure does the gas exert if its volume is decreased to 20.0 mL?
The gas exerts a pressure of 5.00 MPa.
This appears to be a Boyle's Law problem.
Boyle's Law is
#color(blue)(|bar(ul(color(white)(a/a) P_1V_1 = P_2V_2color(white)(a/a)|)))" "#
We can rearrange Boyle's Law to get
#P_2 = P_1 × V_1/V_2#
