Question

A boy finds the mass of an iron nail to be 9g. He then takes 15 identical nails and gently
Places them in to eureka can filled with water. The water overflows and is collected in a
Measuring cylinder. The reading noted down from the measuring cylinder is 27ml.
Determine the density of the iron nail.

Answer 1

Answer:

5g/$cm^{2}$

Explanation:

mass of 1 nail is 9 gram

so, mass of 15 nails is 15 multiplied by 9 i.e. 135 gram

volume is 27 ml

since, 1 ml = 1 $cm^{3}$

so, volume is 27 cm^3

then, density = mass/volume

so, density = 135 g/27 cm^3

therefore, density = 5 g/ cm^3
