7. A mining company find a deposit of metal. Based on the other intensive properties it could be iron (7.9 g/cm), lead
(11.3 g/cmº), or nickel (8.9 g/cm.).
A 15 cm sample of it weighs 134g. Which metalis it most likely to be?

Answer:

Nickel

Explanation:

Given data:

Density of iron = 7.9 g/cm³

Density of lead = 11.3 g/cm³

Density of nickel = 8.9 g/cm³

Mass of sample = 134 g

Volume of sample = 15 cm³

Which metal it is = ?

Solution:

First of all we will calculate the density of sample and then match it with the density of given metals.

Formula:

d = m/v

by putting values,

d = 134 g/ 15 cm³

d = 8.9 g/cm³

The weighted sample is nickel metal.
