What is the molality of an aqueous solution containing FeCl3 (MM = 162.2 g/mol) with a mole fraction of FeCl3 of 0.15?
Natalka [10]

Answer:

10 m

Explanation:

The mole fraction of FeCl₃ of 0.15, that is, per mole of solution, there are 0.15 moles of FeCl₃ and 1 - 0.15 = 0.85 moles of water.

The molar mass of water is 18.02 g/mol. The mass corresponding to 0.85 moles is:

0.85 mol × 18.02 g/mol = 15 g = 0.015 kg

The molality of FeCl₃ is:

m = moles of solute / kilogram of solvent

m = 0.15 mol / 0.015 kg

m = 10 m

Calculate the ratio of effusion rates for nitrogen (n2) and neon (ne)
max2010maxim [7]
The   ratio  of  effusion   rates  for  nitrogen  and   neon   is  calculated by use  of the  Grahams  law  formula

that  is rate  of N2/  rate  of  Ne  =  square  root  of   mm of  Ne/mm   or N2

=square  root   of  20.18/28 = 0.849
