100g

of an ideal gas is kept in a cylinder of

416L

volume at

27 ° C

under

1 . 5

bar pressure. The molar mass of the gas is

g{mol}^{- 1}

. (Nearest integer)
(Given :

R = 0 . 083L

bar

{K}^{- 1}{mol}^{- 1}

)

Correct answer

0

Step-by-step solution

$PV = nRT$

$1 . 5 \times 416 = \dfrac{100}{M . wt} \times 0 . 083 \times 300$

M.Wt. $= 3 . 99 = 4g / mole$
