If the solubility of a gas in water is 0.77g:L at 3.5 atm or pressure, what is it’s solubility in g/L at 1.0 atm pressure? Temperature is constant at 25C.

4nh3+5o2--> 4no+6h20what is the total number of moles of h2o produced when 12 mole of nh3 is completely consumed?

How many mmols of tris-hcl are there in 100 ml of a 100 mm tris-hcl buffer solution at ph 8.1? note that the 100 mm refers to the sum of tris and tris-hcl concentrations?

At 20°c, a sample of h2o liquid and a sample of co2 gas each have the same average kinetic energy. why is one a liquid and the other a gas at this temperature?
