A student needs a 15% hydrochloric acid solution for a chemistry lab. How much 20% hydrochloric acid should she mix with 60 mL of 5% acid to get a 15% solution? a) Use a TABLE to clearly and completely organize the information. Be sure to correctly label EACH row and column. If necessary, use variable names that make sense in the context of the problem (do not usex or y). b) Use your answer to part a to set up a linear equation in one variable that can be solved to determine the how many mL of 20% hydrochloric acid are needed. The equation must pull directly from the table c) Rewrite and solve your equation from part b. You must solve a single-variable linear equation
