Question

A student filled a graduated cylinder with water and read the meniscus at 36.1 mL. The student then
dropped a metal cylinder into the graduated cylinder and the water level rose to 43.7 mL. If the metal
cylinder had a density of 2.70 g/
mL, determine the mass of the solid object. Show work.

Answer 1

Answer:

The mass of solid object is 20.52 g.

Explanation:

Given data:

Volume of water = 36.1mL

Volume of water with metal cylinder = 43.7 mL

density of metal cylinder = 2.70 g/mL

Mass of solid object  = ?

Solution:

First of all we will calculate the volume of solid object.

Volume of solid object = Volume of water with metal cylinder  - Volume of water

Volume of solid object =  43.7 mL - 36.1mL

Volume of solid object =7.6 mL

Density:

density = mass/ volume

2.70 g/mL = mass / 7.6 mL

mass =  2.70 g/mL × 7.6 mL

mass = 20.52 g

The mass of solid object is 20.52 g.
