A gas contains 350 ppm of H2S in CO2 at 72°F and 1.53 atm pressure. If the gas is liquified, what is the weight fraction H2S?
You are asked to make up a laboratory solution of 0.10 molar H2SO4 from concentrated (96%) H2SO4 @ 56°F. The barometric pressure reads 750 mmHg. You look up the specific gravity of 96% H2SO4 and find it is listed at 1.858. Calculate:
(a) The weight of 96% acid needed per L of solution.
(b) The volume of 96% acid used per L of solution.
