Question

the mass of a mineral is 9.6g the mineral is placed in a graduated cylinder containing 8.o mL of water. the water level rises to 16.0 mL. what is the mineral's density?

Answer 1

The volume of the mineral = increase in volume of the water whuich is 16 - 8 = 8mls.

Therefore the mineral's density = 9.6 / 8

= 1.2 g/ ml answer

Answer 2

The density of mineral is:

1.2 g/mL

Explanation:

It is given that:

when a mineral with mass 9.6 g is placed in a cylinder with 8.0 mL of water then the water level rises to: 16.0 mL

This means that:

The volume of mineral is:

Volume of the water level after the mineral-Original volume of water in cylinder.

= 16-8

= 8 mL

Now, we know that the density of a substance is the ratio of mass to volume .

i.e.

`\text{Density}=\frac{\text{Mass}}{\text{Volume}}`

Hence, the density of substance will be:

`\text{Density}=(9.6)/(8)g/mL`

i.e.

`\text{Density}=1.2g/mL`
