Question

5 litres of alcohol has a mass of 4 kg calculate the density of alcohol in gram per centimetre cube

Answer 1

Hey mate !!

Here's the answer !!

We know that,

Density = Mass / Volume

1 kg = 1000 g

1 l = 1000 cm³

Therefore in the question they have asked density in g / cm³. Therefore by conversion process we get,

5 l = 5 * 1000 cm³ = 5000 cm³

4 kg = 4 * 1000 g = 4000 g

Therefore Density = 4000 g / 5000 cm³

=> Density = 4 g / 5 cm³ ( Cancelling out the zeros )

=> Density = 0.8 g / cm³

Hope my answer helped !!

Cheers !!

Answer 2

Given,
volume:5liters=5000cm³
mass:4kg=4000g
A/Q
density=mass/volume
density=4000/5000
density=0.8gcm³

hence,density of alcohol is 0.8gcm³
