Stomach secretions are made up of hydrochloric acid, several enzymes, and a mucus coating that protects the lining of your stomach. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. It also eliminates bacteria and viruses in the stomach, protecting your body from infection.

Answer:

130 μL

Explanation:

The dilution formula is used to calculate the volume V₁ required:

C₁V₁ = C₂V₂

V₁ = (C₂V₂)/C₁ = (2.00L)(0.001M)/(15.0M) = 1.3 x 10⁻⁴ L or 130 μL

(1.3 x 10⁻⁴ L)(10⁶ μL/L) = 130 μL
