You need a 25% alcohol solution. On hand, you have a 225 mL of a 35% alcohol mixture. How much pure water will you need to add t
Radda [10]

You will need 252 mL of pure water to obtain 0.25 mL of the desired 25% solution.

If we add X amount of water to the solution, the total amount of solution is 375+X.

And that must be 25%.

<h3>What is the amount of solute in the current solution?</h3>

The amount of solute in the current amount of solution is

0.6(375)=225.

That amount won't change by adding water.

So we set up the equation so that the amount of solute divided by the new total amount of solution equals 25%.

225/(375+X)=0.25

cross multiply and solve

225/0.25=(375+X)

900-375=X

X=525

The pure water will you need to add to obtain the desired solution is 525.

Then we check 225/(375+525)=0.25.

Answer:

2/7 divided 7= 2/14=1/7

Step-by-step explanation:

In these kind of problems you keep,change,flip

2/7 stays the same the division symbol change to a multiplaction sign and since the 7 is a whole we have to change it to 7/1 and flip it so the answer is   2/14 and since 2 goes into 14 we can simply when change to 1/7

HHope this helps :)
