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

gladu [14]

Answer:

There are 30 ounce of green paint 18 ounces blue paint was needed.

Step-by-step explanation:

Given that,

In order to make green paint a 2:3 ratio of blue paint and yellow paint is used.

Assume 2x blue paint and 3x yellow paint required to make 30 ounce of green paint.

According to the problem,

2x+3x=30

⇒5x=30

$\Rightarrow x=\frac {30}{5}$

⇒ x=6

The amount of blue paint is = 2×6

=12 ounces

The amount yellow paint is = (3×6)

= 18 ounces

There are 30 ounce of green paint 18 ounces blue paint was needed.
