As we know , density = mass/volume ..
Here vol and density is given ..
So mass = D*V
= 13.6*1000 .
= 13600g ..
Now moles = given wt/ molecular wt ...
13600/200
= 68 moles

Number of ‘moles’ of “Mercury” = 68 moles
Solution:
The number of moles present is calculated using the formula:
Number of moles = Mass of the substance in g or Molecular mass in g
Molar (atomic) mass of Mercury (Hg) = 200
Mass of a substance
Volume of mercury = 1 litre = 1000
Density of liquid mercury = 13.6
Mass of Mercury (M)
M = 13600g
Number of moles of Mercury
