Question

Eliza places an 18-gram piece of an unknown substance into a graduated cylinder that is filled with 5 mL of water, and the water rises from the 5 mL line to the 8 mL. What is the density of the unknown substance in g/mL?

Answer 1

I think its 6g or 16g but im pretty sure its 6g

Step-by-step explanation:

Answer 2

6g/mL

Step-by-step explanation:

Given parameters;

Mass of the unknown substance = 18g

Volume of water before the mass is introduced = 5mL

Volume of water after the mass is introduced = 8mL

Unknown:

Density of the mass = ?

Solution:

Density is the mass per unit volume of a substance.

Density =
`(mass)/(volume)`

Mass is the amount of matter in a substance

Volume is the space occupied by a body

Volume of the body = 8mL - 5mL = 3mL

Insert the parameters and solve;

Density =
`(18g)/(3mL)` = 6g/mL
