Show the calculation for the mass of NaNO_2 required to produce 40. mL of N_2 with a temp. of 25.6 degrees C and an atm. pressure of 739 mmHG.
Please give a good simple step by step solution on how to solve the problem.© BrainMass Inc. brainmass.com February 24, 2021, 2:31 pm ad1c9bdddf
First you need a chemical reaction producing N_2 gas.
2 NaNO_2 --> 2Na + N_2 + 2 O_2
use the ideal gas law to figure out how many moles of N_2 gas that is.
n = PV/RT
V = 40 mL = 0.040 ...
The solution gives a step by step answer to finding the mass of NaNO2 required to produce a certain amount of N2 under given conditions in a clear manner with explanation throughout.
