Problem- What is the volume of .712 M ammonium sulfate contains 8.90 g of ammonium ion?
Can you please show me how it's done? I want you to clarify the chemistry in this above problem.
Calculate the solubility (in M units) of ammonia gas in water at 298 K and a partial pressure of 7.50bar . The Henry's law constant for ammonia gas at 298 K is 58.0 M atm and 1 bar = 0.9869 atm.
