Question

Please help :< I'm not sure if I'm doing this correctly... An empty graduated cylinder weights 82.450g. When filled to 50.0mL with an unknown liquid it weighs 110.810 g. What is the density of the unknown liquid? Do I do, d= m/v so,82.450/50.0mL, Also, my teacher is very specific with significant figures for chemistry (so I hope it will be the correct sig fig? The person is vague but very picky) Thank you! :)
(I asked this in the chemistry section but I hope those in the mathematics section know this).

Answer 1

The answer is .567g/mL. Here's my work if you can read my poor handwriting
