Homework Help: Chemistry

Posted by David on Monday, October 4, 2010 at 5:56pm.

A graduated cylinder massed at 34.56g and then 8.6 ml was added of an unkonwn liquid this brought the mass to 45.87g. What is the density?

I'm not sure how to go about this. Is the 34.56g unneccessary information?

Or, do you subtract 45.87-34.56= 11.31 then do mass 11.31/volume8.6 = 1.315 which in sig fig is 1.3g/ml
