Question

The mass of sample X is 20.Og. It was placed in a graduated cylinder and the water level rose from A (14 mL) to B (19 mL). What is the density of sample X? Pay close attention to significant figures. g/mL​

Answer 1

The density of sample X is 4 g/ml.

The given parameters;

• Mass of sample X = 20 g
• Initial volume of water before the sample was placed = 14 ml
• Final  volume of water after the sample was placed = 19 ml

The volume of the sample X is the increase in the volume of water after it was placed in the cylinder.

• Volume of sample X = 19 ml - 14 ml = 5 ml
• Mass of sample of X = 20 g

The density is obtained by dividing the mass of sample X by its volume as shown below;

$Density = \frac{mass}{volume} = \frac{20}{5} = 4 \ g/ml$

Thus, the density of sample X is 4 g/ml.
