To find the mass of the ammonia, you can use the ideal gas equation, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. Rearrange the equation to solve for n: n = PV/RT. Substitute the given values into the equation and calculate the number of moles of ammonia. Finally, multiply the number of moles by the molar mass of ammonia (17 grams/mol) to find the mass of the ammonia present in the sample.
Given the ideal gas constant R = 0.0821 L-atm/mol.K, you can use this value in the rearranged ideal gas equation n = PV/RT. Substitute the given values of P (1.2 atm), V (3.7 L), T (290K), and R into the equation to calculate the number of moles. Multiply the number of moles by the molar mass of ammonia (17 grams/mol) to find the mass of the ammonia.
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.
