Question 4 L2.2
Boyle's law is

P. V1 = P2V2 A balloon has an initial volume of 355 L and an initial pressure of 234 kPa.

The volume is lowered to a final value of 227 L Use Boyle's Law to calculate the final pressure.
Round to two decimal points and do not use units.

Question 5
L2.3

The ideal gas law equation is

PV=nRT

How many moles of gas are in closed container with a pressure of 400 kpa, volume of 10L and a temperature of 450 K?

use 8.31 L * kpa/K * mol for R​
