Question

Please find these numerical 4, 5
.please

Answer 1

Density = Mass / Volume

So Volume = Mass / Density

To convert density from g/cm3 to kg/m3 multiply the number to 10^3.

So here density is 0.6.
0.6 * 10^3 = 600kg/m3

Now put it in formula

Volume = 600kg / 600kg/m3
= 1m3

So Volume is 1m^3

Answer 2

4.density =mass /volume
density=0.6g/cm^3
=600kg/m^3
mass=600kg
volume=mass /density
=600kg/600kg/m^3
=1m^-3
5. volume 2litre=2000cm^3
mass
1.6kg
density=mass /volume
density=1.6kg/2000cm^3
density=16kg/20000cm^3
density=4/5000kg/cm^3
density=8×10^-3kg/cm^3
