Title: Conetration/Percent by mass
Post by: elajhaw on February 23, 2017, 12:09:15 PM

A solution is mad containing 22.8g of magnesium nitrate per 325g of water.
What is the weight/weight % or percent by mass of the solute?

I have tried twice to answer this and I don't seem to be getting it right. I know that for weight weight % you divide the two weights and then multiply by 100 to get the percent, but it's still incorrect. *delete me*(:
