Question
Small quantities of hydrogen gas can be prepared in the laboratory by the addition of aqueous hydrochloric acid to metallic zinc according to the following balanced equation:
Zn (s) + 2HCl (aq) ----> ZnCl2 (aq) + H2 (g)
The hydrogen gas bubbled through water for collection and becomes saturated with vapor water. Suppose 240. mL of hydrogen gas is collected at 40.0 C and has a total pressure of 1.030 atm by this process, How many grams of zinc must have reacted to produce this quantity of hydrogen?
Explanation / Answer
The vapor pressure of water at 40
