Atomic mass of mercury is 200 and density is 13.6 g `cc^(-1)` . How many moles of metal are present in one litre ?

Text Solution

Verified by Experts

weight of Hg `= "volume "xx"density" = 1000xx13.6=13600g`
Number of moles `("weigt")/("GAW")=(13600)/(200)=68`
One litre of mercury contains 68 moles
