Chemistry density help?

Question

An empty graduated cylinder weighs 82.450 g. When filled up to 50 mL with an unknown liquid it weighs 110.810 g. What is the density of the unknown liquid?

Answer 1

110.810 - 82.450 = 28.360 g / 50 mL = 0.57 g/mL

Answer 2

Density= Mass/Volume

1.  Find the mass of the unknown liquid by subtracting 82.450g from 110.810g.  The answer is 28.360g

2.  Find the density by using the equation d=m/v

     d= 28.360g/ 50ml

     d=0.57g/ml
