Agraduated cylinder contains 20.5 ml of liquid weighed 110.4567 grams. if the density of the unknown liquid is 0.9856 g/ml, what is the weight of the graduated cylinder when it's empty? (show your work)

90.3 g

Explanation:

Calculate the mass of the liquid

D = M/V                    Multiply both sides by V and transpose

M = V × D

V = 20.5 mL

D = 0.9856 g/mL     Calculate M

M =20.5 × 0.9856

M = 20.20 g

Calculate the mass of the cylinder

Mass of cylinder = mass of (cylinder + liquid) – mass of cylinder

Mass of cylinder + liquid = 110.4567 g     Calculate mass of cylinder

Mass of cylinder = 110.4567 – 20.20

Mass of cylinder = 90.3 g
