How many mL of the 3.00 M HCl stock solution is needed to prepare 250.0 mL of a 1.10 M HCl solution?

91.7 mL are needed to prepare the diluted solution

Explanation:

When you dilute a determined solution  the molarity and the volume for both solutions (diluted and concentrated), are the same.

M concentrated . Concentrated volume = M diluted . Diluted volume

3 M . Concentrated volume = 1.10 M . 250 mL

Concentrated volume → ( 1.10 M . 250 mL) /  3M = 91.7 mL

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
