Question

a piece of material weighing 50g is coated with 6.3g of wax of relative density 0.9. If the coated piece weighs 16.3g in water the density of the material is.

Answer 1

Hey Mate ⭐⭐⭐

Here's ur answer ⤵

=>50+ 6.3 = 56.3 g

=>56.3 g - 16.3 g=40. G

Volume of water displaced is 40 cm.

50/p + 6.3/9=40

50/p=33

p= 50/33

=> p= 1.515

If the coated piece weighs 16.3 g in water, the density of the material is ρ = 1.515

Hope it helps you! ヅ
