The ideal gas law : PV=nRT relates pressure P, volume V, temperature T, and number of moles of a gas, n. The gas constant R equals 0.08206 Lâ atm/(Kâ mol)or 8.3145 J/(Kâ mol). The equation can be rearranged as follows to solve for n: n=PVRT
1. When heated, calcium carbonate decomposes to yield calcium oxide and carbon dioxide gas via the reaction
CaCO3(s)âCaO(s)+CO2(g)
What is the mass of calcium carbonate needed to produce 75.0 L of carbon dioxide at STP?
2. Butane, C4H10, is a component of natural gas that is used as fuel for cigarette lighters. The balanced equation of the complete combustion of butane is 2C4H10(g)+13O2(g)â8CO2(g)+10H2O(l)
At 1.00 atm and 23 âC, what is the volume of carbon dioxide formed by the combustion of 3.80 g of butane?
