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-atm
mol.K calculate the mass.
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.
To find the mass of the ammonia gas, we can use the ideal gas equation, which states that 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. Rearranging the equation, we have n = PV/RT.
Firstly, we need to convert the pressure to units of atm. Secondly, we can substitute the known values into the equation and solve for the number of moles. Finally, we can multiply the number of moles by the molar mass of ammonia (17 g/mol) to obtain the mass of the ammonia gas.
