A chemist has 200 ml of a 10% sucrose solution. If she adds x milliliters of a 40% sucrose solution, what is the percent concentration of the final mixture? which expression represents the total mass, in grams, of sucrose in the final mixture? which expression represents the total volume, in milliliters, of the final mixture?.

Being focused in some way. attention being focused on a single thing, in particular. I can't concentrate with all that noise around me. a concentration or major within an academic discipline.

What is volume?

A three-dimensional space's actual size when a closed surface encloses it. Take the area or shape that a substance, such as a solid, liquid, gas, or plasma, occupies as an example. The cubic meter, a S.I.-derived unit, is also frequently used to represent volume numerically.

We take the amount times the percent concentration and add what we mix to get the final concentration

We need the final mixture to be 30% and we have 200 +x milliliter added together so that will be the amount in the container

200 * 10 % + x* 40 % = (200+x) *30%

Change the percent to decimal form

200 * .10 + x* .40 = (200+x) *.30

Distribute the .30

20 + .4x = 60+.3x

Subtract .3x from each side

20 + .4x-.3x = 60+.3x-.3x

20 +.1x = 60

Subtract 20 from each side

20-20 +.1x = 60-20

.1x = 40

Divide by .1

.1x/.1 = 40/.1

x=400

Therefore, We need to add 400 ml of the 40% solution
