a mass of air has a pressure of 100. kPa and a volume of 200. L. If it is compressed to a new volume of 80.0 L, what will be the new pressure?

Plz show me how to solve the problem step by step.  Thank you!

been a long time but I think

$$p_1 v_1 = p_2 v_2 \\ 100~kPa \cdot 200~L = p_2 ~kPa \cdot 80~L \\ p_2 = 250~kPa$$
