Question

An iron cube of mass 117g is immersed in a measuring cylinder with Water at the 30cm 3 mark. The water level went up to the 45 cm 3 mark. Calculate the density of iron.

Answer 1

Answer:

7.8g/cm³

Explanation:

mass of iron =117g

change in volume of water = net volume of iron cube ( by archimedes principle)

so change in volume of water = 45-30 = 15 cm³

we know, density = mass /volume

so density of iron = 117g/15cm³ =

7.8 g/ cm³
