Tu and noke are working with a red food coloring, red #40. the stock solution has a concentration of 0.0880 m dye. noke want to makes a concentration of 0.0088 m, exactly one tenth of the original red dye solution strength. what volume of the original 0.0880 m solution should she measure into a 100.0 volumetric flask, to be diluted with water up to the line of the flask?

The volume of the original solution is 10.00 mL.

Explanation:

We have a concentrated solution of C₁ = 0.0880 M and we want to prepare 100.0 mL (V₂) of a dilute one of C₂ = 0.0088 M. To calculate the volume of solution 1 (V₁) to be diluted we use the dilution rule.

C₁.V₁=C₂.V₂

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
