Calculate the volume of 2% red dye stock solution required to add to 75 mL of water to obtain a 1:10 diluted?

Answer 1

Impossible.

2% would mean that the dye itself is 1: 50 diluted, adding it to water would make it more diluted no matter what amount both are, as you can't increase the % of the dye by adding water, you would only be decreasing the % and therefore never getting 1:10 diluted solution.

Adding it to 1 ml of water already, would be making it more diluted, even if you keep adding the 2% solution of red dye, the ratio will only get closer to 1:50, never 1: 49 or 1: 48 etc.

You are trying to get a 10% red dye solution by adding 2% red dye solution to water?

How does that make sense? Please read your question again carefully!

Answer 2

a million:10 potential a million of pink dye to 10 of water. so the respond may be 50 mls of water. in spite of the shown fact that, you probable wrote down the question incorrect as dilutions are regularly defined as a million in 10 quite of a million:10. thus a million/tenth of the suitable soution could be pink dye and the different 9/tenth could be water. To make the answer you will possibly upload 5 mls of pink dye inventory to 40 5 mls of water to make an exceptionally final quantity of fifty mls. The "2%" is in basic terms a decoy to confuse the subject.

Answer 3

5*75ml
