Question

one liter of helium gas has a mass of 0.18 g while one liter of nitrogen gas has a mass of 1.25 g determine the densities of helium gas and nitrogen gas in g/cm
​

Answer 1

Answer: * Density of Helium =0.00018 g/cm³

* Density of Nitrogen = 0.00125 g/cm³

Explanation:

First , we need to convert litres (l) into cubic centimeters (cm³)) .

* 1 litre = 1000 cm³

Second , put the values in the formula.

Density = Mass / Volume

* Of Helium

D = 0.18 g/ 1000 cm ³

D = 0.00018 g / cm

*Of Nitrogen

D = 1.25 g / 1000cm³

D = 0 .00125 g/ cm³
