Question 23 (1 point)

A student is given an object with a mass of 14.8 grams. When placed into a
graduated cylinder the water level rises from 25.0 mL to 34.7 mL.
What is the density of the object and would you expect it to float or sink in the
graduated cylinder if water has a density of 1.00 g/mL? Show all of your work.

Answer 1

d = 1.53 g/mL

Object will sink into water

Step-by-step explanation:

Given data:

Mass of object = 14.8 g

Initial volume of water = 25.0 mL

Final volume after adding object = 34.7 mL

Density of object = ?

Density of water = 1.00 g/mL

Solution:

Volume of object = Total volume - volume of water

Volume of object = 34.7 mL - 25.0 mL

Volume of object = 9.7 mL

Density of object;

d = mass/volume

d = 14.8 g / 9.7 mL

d = 1.53 g/mL

The density of water is 1.00 g/mL which means object is heavier than water thus object will sink into the water. The object with density less than water are float in it.
