Question

plzzzz solve it friends......

Answer 1

heyaa!!

HERE IS UR ANS:-

M in the equation is Molecular Weight of the gas.Thus its unit is gm/mole

HOPE THIS MAY HELP U ^--^

Answer 2

we have to find unit of M in the given equation $\bf{PV=\frac{w}{M}RT}$

first of all, you should know about all given symbols.
here P denotes the pressure, V denotes volume , w denote weight in gram , M denotes molecular mass , R denotes universal gas constant and T denotes temperature.

now you say me what is the unit of molecular mass /weight . of course, gm/mol
because molecular mass/weight is the the mass of one mole of a molecule.

hence, answer is gm/mol
