Is the following right the reason I ask is because I read a paper online thst said you can get 50 liters or 1.76 cuft of ammonia gas from 1 liter of ammonium hydroxide.
i have a solution of ammonia hydroxide 16oz at room temp 65f that has a concentration of 28 percent ammonia. I want to know how much ammonia gas in cubic feet I can get from that solution.
Following is the reason:
OK, so I will look up the density. It is 0.89 g/mL. I'll use 1L for the volume.
0.89 g/mL X 1000mL = 890g NH3
890g / 17 g/mol = 52.35 mols
1atm X V = (291K)(0.082)(52.35)
1249L of NH3 gas = 44 cuft (theoretical if you isolated the entire amount).
This is slightly wrong. You have assumed the the density of the solution (0.89 g/ml) is the cocentration of NH3 in solution. It is actually 28% ammonia (NH3) in water.
1L of solution will have 28% of 890g of NH3g. Or 249.2g.
The rest of your reasoning is correct.
Be carefull if you try to make this gas in practice I once cleared a building with ammonia gas.
It is also flammable above 15% in air.
I hope this helps.
