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

    Mass empty cylinder = 34.56g
    mass cylinder + liquid = 45.87g
    The difference is the mass of the 8.6 mL of the liquid that was added.
    Density = mass/volume

    so did I do it right?

    You did it exactly right. Bravo! I didn't scroll down far enough to see the bottom of the post where you had worked it out.
