Molarity
mol/l
n = gmol = N molecules / N Avogadro n = ( 2.4 x 10^23 molecules ) / ( 6.022 x 10^23 molecules per gmol ) n = 0.3985 gmol m = ( n ) ( M ) m = ( 0.3985 ) ( 141.94 g per gmol ) = 56.6 g <----------------------
mol/L
Molar Mass
The mass of 35 gmoles of carbon monoxide ( CO ) is given by : m = ( n ) ( M ) m = ( 35 gmol ) ( 28.00 g / gmol ) = 980 g <----------------

The average molecular weight of dry air is 28.96 g/gmol.
1molar=58.44gmol as given so,58.44-1000ml ? -200ml ans=58.44.200 ---- 1000 =
