nitrate. A link to the periodic table is provided for you.
g/mol
Answer: 61.98 is correct
Explanation:
Molar mass of calcium nitrate is 164 g/mole which is obtained by adding atomic weights of constituent elements.
What is molar mass?
Molar mass of a compound or a molecule is defined as the mass of the elements which are present in it.The molar mass is considered to be a bulk quantity not a molecular quantity. It is often an average of the of the masses at many instances.
The molecular mass and formula mass are used as synonym for the molar mass.It does not depend on the amount of substance which is present in the sample.It has units of gram/mole.
Molar masses of an element are given as relative atomic masses while that of compounds is the sum of relative atomic masses which are present in the compound.
Molar mass of calcium nitrate =40+[14+(16×3)]×2=164 g/mole.
Thus, the molar mass of calcium nitrate is 164 g/mole.
