Given the mass percentage of Manganese in a normal healthy body is
It means that g Mn is present in 100 g of the body mass.
Given that the person weighs 196 lbs
Converting the person's mass to g: The conversion factors to be used are: 1 kg = 2.205 lb; 1 kg = 1000 g
Calculating the mass of Mn in the person's body:
Therefore, 0.116 g Mn is present in a person weighing 196 lbs.
Sharing of electrons always means its a covalent bond, and unequal means it is polar, so it is a polar covalent bond
