You need to create a set of standard dilutions from a stock solution that has a a concentration of 0.750 m. you begin by taking 2.00 ml of stock solution and adding 8.00 ml of water for your first dilution. what is the concentration of the resulting solution?

The concentration of the resulting solution is 0.15 M.

Explanation:

Stock solution

0.750 mol 1000 mL

       x         2.00 mL

            x = 1.5 x 10⁻³ mol

Resulting solution:

1.5 x 10⁻³ mol 10.00 mL

       y              1000.00 mL

            y = 0.15 mol

The concentration of the resulting solution is 0.15 M.

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

it would be a gas formation
