A graduated cylinder containing 40 mL of water has a total mass of 60 g. A solid object carefully lowered into the graduated cylinder. The level of the water rises to 70 mL. The total mass of the cylinder, water and object is now 95 g what is the mass? volume? and density

The correct answer is -

A) 35 g

B)30 mL

C)1.66666666666667g/ml3

Explanation:

Given:

mass of graduated cylinder containing 40 mL = 60 g

volume of water = 40 ml

increase in the level of water = 70 ml

increase in mass = 95

Solution:

A) mass of object -

increased mass - initial mass

90 - 60 = 35 g

B) volume of object

increased volume - initial volume

70 - 40 = 30 mL

C)  density d=m/v

d=35/30

d=1.66666666666667
