Ok, I am definitely victim to the use it or lose it crowd when it comes to math. This is a simple problem but I'm lacking the confidence my logic with it. so, I want to make a 3L solution. To make a 1L solution, I add 100mL of this 10X reagent with 900mL of water. I must then add 700g of a powder to this solution. In the end, the final volume comes out to be 1400mL. For the sake of my own curiosity, how do I go about solving this? Here's what I've reasoned... 700g for 1400mL to make 3000mL, 3000/1400 = 2.14 700g x 2.14 = 1498g 100 x 2.14 = 214mL of 10x soln 900 x 2.14 = 1926mL of water ~~~~ with the outrageous amount of powder, I should get 3L. Am I right or wrong? Please help me out with this. thanks

If I understood your reasoning, wherein the fundamental idea was that 2.14 time the original volume requires 2.14 the original ingredients, I agree with you.

Hi TreeTruffle, if you've already posted a problem elsewhere, please provide a link instead of a duplicate post, so that we don't just tell you what you've already been told on the other site.
