A gas contains 350 ppm of H_{2}S in CO_{2} at 72°F and 1.53 atm pressure. If the gas is liquified, what is the weight fraction H_{2}S?
You are asked to make up a laboratory solution of 0.10 molar H_{2}SO_{4} from concentrated (96%) H_{2}SO_{4} @ 56°F. The barometric pressure reads 750 mmHg. You look up the specific gravity of 96% H_{2}SO_{4} 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.
