Question

wht is meant by vapour density and molar mass

Answer 1

1️⃣Vapour density:

✔️It is the ratio of the mass of a volume of a gas, to the mass of an equal volume of hydrogen, measured under the same conditions of temperature and pressure.

2️⃣Molar mass:

✔️It is the mass of one mole (or 6.023 X 1023) particles of that substance. The molar mass of a substance is numerically equal to the atomic mass or the molecular mass of the substance in ‘u’ and  is always expressed in grams (or sometimes Kg). For example, the molar mass or mass of 6.023 X 1023 molecules of glucose is 180g. Similarly, mass of 6.023 X 1023 atoms of sodium or molar mass of sodium is 23g, but its atomic mass is 23u.

VAPOUR DENSITY-----

It refers to that density of the vapour to that of hydrogen at a same temperature...

It can be calculated as follows - - -



VAPOUR DENSITY = mass of n molecules of vapour / mass of n molecules of hydrogen..
