eral Chemistry 1 Workshop 12. Gases Here are some equations and constants you may need to solve the problems in this workshop: PV = nRT Mw=m/n KE = 12 mv² KE = (3/2) nRT R = 0.08206 L-atm/mol-K Part 1. Exploring Ideal Gas Law Consider a 75.0 L balloon that contains 3 moles of an ideal gas at 750 mm Hg and 27°C. A. PREDICT (don't do any calculations yet) and EXPLAIN: For each of the conditions below, state if the variable in question will increase, decrease or stay the same. Briefly explain each of your answers using the ideal gas law. a) If V decreases by 33 L (but T and n stay constant), what happens to P? b) If Tincreases to 67 °C (but P and n stay constant), what happens to V? c) If P decreases to 610 mm Hg (but V and n stay constant), what happens to T? d) If you add 2.0 mol of gas to the balloon (while T and P stay constant), what happens to V?

Question
How can we predict a-d with the moles?
eral Chemistry 1 Workshop 12. Gases Here are some equations and constants you may need to solve the problems in this workshop: PV = nRT Mw = m/n KE = ¹2 mv² KE = (3/2) nRT R = 0.08206 L-atm/mol-K Part 1. Exploring Ideal Gas Law Consider a 75.0 L balloon that contains 3 moles of an ideal gas at 750 mm Hg and 27°C. A.

B. SOLVE: Now solve all of the problems mathematically using PV = nRT for a double-state problem. Give answers in the same units that are used in the problem, pay attention to sig figs. 2
