Well, which do you think and why?

Answer 24

Honestly I don't get this question I need all the help. Which do you think?

Answer 25

I know the answer.

With a system like this, you have two concepts that are working together to make the answers. The first concept is that two volumes of different concentrations are added to make a new concentration. The other is that two volumes are added to make a total volume.

nevermind, thanks for your help.

OK, lets look.
0.1x+0.6y=0.4(5)
x+y=5

B. Eunice needs to combine solutions of 0.1M HCl and 0.6M HCl to produce 5L of 0.4M hydrochloric acid (HCl).

Yes.

If x is the 0.1M HCl and y is the 0.6M HCl then:
0.1x+0.6y=0.4 \(\leftarrow\) the 0.1 and 0.6 mixed make 0.4
x+y=5 \(\leftarrow\) the total volumes should add to 5.
