Ammonia gas has a molar mass of approximately 17 grams per mole. At 290K and 1.2 atm, a sample of ammonia has a volume of 3.7 L. In three to five sentences, explain how you can find the mass of the ammonia. Then, given R=0.0821L⋅atmmol⋅K , calculate the mass.
To find the mass of the ammonia gas, we can use the ideal gas law equation: PV = nRT. Since we have the pressure (1.2 atm), volume (3.7 L), and temperature (290K), we can rearrange the equation to solve for the number of moles (n) of ammonia gas in the sample. Then, we can multiply the number of moles by the molar mass of ammonia (17 g/mol) to calculate the mass. Given R = 0.0821 L⋅atm/mol⋅K, we have all the necessary information to solve for the mass of the ammonia.
