Question

The density of a metal is 10.5 g/cm3. If the mass of themetal

is 5.25 g and it is placed in 11.2 ml of water, how much willthe
water rise?

Answer 1

11.7 mL

Step-by-step explanation:

Density of a substance is given by the mass of the substance divided by the volume of the substance .

Hence , d = m / V

V = volume

m = mass ,

d = density ,

From the question ,

The density of the metal = 10.5 g/cm³

The mass of the metal = 5.25 g

Hence , the volume can be calculated from the above formula , i.e. ,

d = m / V

V = m / d

V = 5.25 g / 10.5 g/cm³

V = 0.5 cm³

Since , The unit 1 mL = 1 cm³

V = 0.5 mL

The vessel has 11.2 mL of water ,

The new volume becomes ,

11.2 mL + 0.5 mL = 11.7 mL
