1. The Ideal Gas Law equation is PV=nRT. Define each variable and include the unit necessary for each variable in the equation.

2. What is the pressure in a vessel of 4.5g of O2 gas that takes up a volume of 4.2 L and is at a temperature of 38.2 oC? (Use R = 0.0821 L-atm/mol-K).

3. A vessel of N2 gas was originally at a pressure of 3.4 atm, a volume of 2.3 L, and had a temperature of 21.5oC. If the temperature is changed to 31.5oC and the volume is decreased to 1.8 L, what will the new pressure of the vessel be?

4. Why does the Ideal Gas Law break down at high pressures and low temperatures?

The ideal gas law PV=nRT relates pressure P, volume V, temperature T, and number of moles of a gas, n. The gas constant Requals 0.08206 L⋅atm/(K⋅mol) or 8.3145 J/(K⋅mol). The equation can be rearranged as follows to solve for n: n=PVRT This equation is useful when dealing with gaseous reactions because stoichiometric calculations involve mole ratios. A)When heated, calcium carbonate decomposes to yield calcium oxide and carbon dioxide gas via the reaction CaCO3(s)→CaO(s)+CO2(g) What is the mass of calcium carbonate...
