Answer:
6g/mL
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 = [tex]\frac{mass}{volume}[/tex]
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 = [tex]\frac{18g}{3mL}[/tex] = 6g/mL
