Question

Two cylinders contain 100g of hydrogen and 400g of gas B. if the capacity of
both cylinders and their temperature and pressure is the same, find the
molecular mass of gas B.

Answer 1

The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to the Earth or some parts of Earth.

Volume of the container, temperature and pressure are same for all the gases.

M

= constant

Hence,

= 28 g/mol

Hence, the relative molecular masses of A and B are 44 g/mol and 28 g/mol respectively.
