Question

1. What is the density, in g/cm², of a substance weighing 22.2 cg with dimensions of 0.333

cm by 0.444 cm by 0.555 cm?

Answer 1

• Mass=22.2cg=2.22g

Volume:-

`\\ \tt\longmapsto 0.333(0.444)(0.555)=0.08cm^3`

So

`\\ \tt\longmapsto Density=(Mass)/(Volume)`

`\\ \tt\longmapsto Density=(2.22)/(0.08)=27.75g/cm^3`
