mmonia 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⋅atm/mol⋅K
, calculate the mass.
To find the mass of the ammonia gas, we can use the Ideal Gas Law equation: PV = nRT. Rearranging this equation gives us n = PV/RT, where n is the number of moles of ammonia gas. Since the molar mass of ammonia is given as 17 grams per mole, we can multiply the number of moles (n) by the molar mass to find the mass of the ammonia gas.
Using the given values of P = 1.2 atm, V = 3.7 L, R = 0.0821 L⋅atm/mol⋅K, and T = 290K, we can calculate n using the equation n = PV/RT. Then, we can multiply n by 17 grams/mol to find the mass of ammonia gas.
