To reduce 16 ounces of a 25% solution of antiseptic to a 10% solution, how much distilled water should a nurse add?

yan [13]

Answer:

24 ounces

Step-by-step explanation:

Here's a more intuitive approach to use here.

You know that your initial solution has a percent concentration, presumably volume by volume, of

. This means that any volume of this solution contains

part solute and

parts solvent.

The target solution must have a concentration of

, which means that any volume of this solution will contain

part of solute and

parts solvent.

Your starting solution has a volume of

ounces, or

parts, each with a volume of

ounces.

In order to get to a solution that has a total of

parts, you must add

parts of solvent to the initial solution. Since we know that

1 part

4 ounces

it follows that you must add

parts

⋅

4 ounces

part solvent

24 ounces

of distilled water, which is your solvent, to the initial solution.

The target solution will contain

part solute and

parts distilled water for a total of

parts of solution, and hence have a percent concentration of

So for the rhombus to carry onto itself, it needs to start in one position and end up in that same position. In this case, (x,y) will need to end up on (x,y) after the reflections are done. Here what the options do:

A: y-axis, x-axis, y-axis

(x,y) -> (-x,y) -> (-x,-y) -> (x,-y)

B: x-axis, y-axis, y-axis

(x,y) -> (x,-y) -> (-x,-y) -> (x,-y)

C: y=x, x-axis, y=x, y-axis

(x,y) -> (y,x) -> (y,-x) -> (-x,y) -> (x,y)

D: x-axis, y=x, x-axis, y=x

(x,y) -> (x,-y) -> (-y,x) -> (-y,-x) -> (-x,-y)

The only option that starts as (x,y) and ends as (x,y) is C: y=x, x-axis, y=x, y-axis, therefore making that the correct answer.
