The ideal gas law relates the temperature, pressure and volume of an ideal gas. Suppose the gas inside a particular balloon has an absolute pressure of 3.15×105 Pa and occupies a volume of 5.33×10-3 m3 at a temperature of 16.7°C. How many moles of gas are inside the balloon? (do not enter units) How many molecules of gas are inside the balloon? (do not enter units)

The ideal gas law states that PV = NkgT where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant ko is called the Boltzmann constant and has the value kg = 1.38x10-23J/K. A very common expression of the ideal gas law uses the number of moles, n- N/NA (NA is Avogadro's number, NA=6.021023 per mole). PV...
