A solution of hydrochloric acid has a molarity of 2.25 M HCl. If a reaction requires 5.80 g of HCl, what is the number of moles of solute required? Assume a molecular mass of 36.45 g for the HCl. mol HCl

This question builds on your problem-solving from the previous question.A solution of hydrochloric acid has a molarity of 2.25 M HCl. If a reaction requires 5.80 g of HCl, what volume of solution should be used? Use the number of moles you calculated in the previous question: 0.159 mol HCl. ⇒ 0.0706
