Graham's Law, 
<span>Rate 1 / Rate 2 = √[M2/M1] </span>
<span>Just substitute, remembering M(NO2) = 46 g/mol, </span>
<span>0.850 = √[46/M1]; </span>
<span>Solving, M1 = 63.7 g/mole. The other gas could be SO2, which has molecular weight 63.9 g/mole.</span>

What is the molality of a solution of water and KCl if the freezing point of the solution is –3°C? (Kf = 1.86°C/m; molar mass of
Elina [12.6K]
Some of the solutions exhibit colligative properties. These properties depend on the amount of solute dissolved in a solvent. These properties include freezing point depression, boiling point elevation, osmotic pressure and vapor pressure lowering. Calculations are as follows:

<span> ΔT(freezing point)  = (Kf)mi
3  = 1.86 °C kg / mol (m)(2)
3 =3.72m
m = 0.81 mol/kg</span>
