Homework Help: Chemistry

Posted by Jake on Sunday, May 9, 2010 at 9:42pm.

I have no idea what I'm doing wrong here...

Question: A solution is 0.3% by mass calcium chloride. Therefore, 145 g of the solution contains how many grams of calcium chloride?

My solution:

145g x (0.3g / 100g) = 0.435g

or 0.44g CaCl2

What am I doing wrong? Thank you!
