4. A sample of chlorine gas occupies a volume of 18.35 L at STP. a. How many moles of chlorine are present in this sample?
b. What mass of chlorine gas does this represent?
c. Chlorine gas reacts violently with hydrogen gas to form hydrogen chloride gas. Write a balanced chemical equation for this reaction
d. The sample of chlorine is allowed to react with an excess of hydrogen as described in part (c). How many molecules of hydrogen chloride are formed in this reaction?
e. A solution of hydrochloric acid can be prepared by bubbling hydrogen chloride gas through pure water. If the products of the reaction in part (d) are bubbled through 500.00 mL of water, what is the molar concentration of the hydrochloric acid solution?
