Question

5.6 lit of gas at NTP weigh equal to 8 gm the vapour density of gas is

Answer 1

Density = mass / volume

In this case our mass is 8 grams.

The volume is 5.6 litres

Since density is given as either Kg/m³ or g/cm³ we need to convert the units to matching units.

In our case we convert the litres to cm³.

This becomes :

1000cm³ = 1 litre

5.6 × 1000 = 5600cm³

Density = 8/5600 = 0.0014286 g/cm³
