Molality -
Molality (m) = (number of moles of solute)/(mass of solvent in kg)
- wherein
It is defined as the number of moles of solute present in 1 kg of solvent. It is denoted by m.
Molecular Formula -
The molecular formula shows the exact number of different types of atoms present in a molecule of a compound.
- wherein
For glucose, empirical formula is CH2O .its molar mass is 180 gram.
n = molar mass/empirical formula mass = 180/30=6
Hence molecular formula= C6H12O6
Mole Concept -
One mole is the amount of a substance that contains as many particles or entities as there are atoms in exactly 12 g (or 0.012 kg) of the 12C isotope.
- wherein
one mole = 6.0221367 X 1023
as we know that no. of moles=
so, molality =
n= 4 mol/kg
Option 1)
12
Option 2)4
Option 3)8
Option 4)16
