A chemistry student wants to measure the rate of a chemical reaction. The reaction involves the reaction between zinc and hydrochloric acid. The student weighed out 0.5 grams of zinc and mixed it with 50 mL of 0.5 M hydrochloric acid. The student measured the time it took for the reaction to complete and found it took 3 minutes to produce all the hydrogen gas. Calculate the rate of the reaction in grams of zinc per minute.
