Final answer:
To make 100 mL of a 1.0 M solution of HCl from a 6.0 M solution of HCl, you would need to measure 16.7 mL of the 6.0 M solution and then add enough water to make the final volume 100 mL.
Step-by-step explanation:
To make 100 mL of a 1.0 M solution of HCl from a 6.0 M solution of HCl, you can use the dilution formula C₁V₁ = C₂V₂.
In this case, C₁ = 6.0 M, C₂ = 1.0 M, and V₂ = 100 mL. Let V₁ be the volume of the 6.0 M solution needed. Rearranging the formula, we have V₁ = (C₂V₂) / C₁.
Plugging in the values, we get V₁ = (1.0 M * 100 mL) / 6.0 M = 16.7 mL. Therefore, you would need to measure 16.7 mL of the 6.0 M solution of HCl and then add enough water to make the final volume 100 mL.
