When 5.0g of a nonelectrolyte is added to 25g of water, the new freezing point is -2.5 degrees C What is the molality of the solution? What is the molar mass of the unknown compound

Sagot :

The molality of the solution and the molar mass of the unknown compound is mathematically given as

  • M=1.34
  • 149.25g/mol

What is the molality of the solution, and the molar mass of the unknown compound?

Generally, the equation for the Molarity   is mathematically given as

M=dt/Kt

Therefore

M=2.5/1.86

M=1.34

Therefore

M=wt s/Mol of un*1000/gof solvent

mol of un =5*1000/1.34*25

149.25g/mol

In conclusion,  the molar mass of the unknown compound is

149.25g/mol
