so 10.23g/1.5mL=6.8 g/mL (you round to 6.8 because you must have only 2 significant digits). The result of the difference is positive and therefore the percent error is positive.

About Todd HelmenstineTodd Helmenstine is the physicist/mathematician who creates most of the images and PDF files found on sciencenotes.org. ie.

A solution's density is the ratio between its mass and... You should read through and understand some proof or another -- there is no reason to just take this formula on faith. The order does not matter if you are dropping the sign, but you subtract the theoretical value from the experimental value if you are keeping negative signs. Reply ↓ Todd Helmenstine Post authorJanuary 28, 2016 at 2:15 pm Thanks for pointing that out.

Ready to improve your skills in Percent-Error? I know that I'm looking for the "partial derivative" of density to solve this, but that is a brand new concept for me, which I don't fully understand. $$p=density$$ $$ m=mass$$ Nearly all of the graphics are created in Adobe Illustrator, Fireworks and Photoshop. So: 10.23/1.50 = 6.82g/mL. (6.82/6.93)*100=98.4% yield, or 1.6% error.
