What will be the molarity of the solution containing 18.25 g of HCl ga

1.	What will be the molarity of the solution containing 18.25 g of HCl gas in 500 g of water ?
Answer» 0.1 m 1 M 0.5 m 1 m Solution :Molality is termed as the number of moles of SOLUTE present in 1 kg of solvent. It is denoted by m. Thus, Molality `=("Moles of solute")/("MASS of solvent (in kg)")` ......(i) GIVEN that, Mass of solvent `(H_(2)O)=500 g = 0.5 kg` Weight of HCl `= 18.25g` Molecular weight of HCl `= 36.5 g` Moles of HCl `= (18.25)/(35.6)=0.5` `m= (0.5)/(0.5)=1 m` ...( `:. (i)` )
