Whether 10.0 mole of C or 10.0 mole of
Concept introduction:
The number of moles of a compound is defined as the ratio of the given mass of the compound to the molar or molecular mass of the compound.
The mathematical expression is given by:
Number of moles =
The one mole of any substance is equal to the

Answer to Problem 118A
The number of atoms of 10.0 mole of carbon is equal to the number of atoms of 10.0 mole of calcium.
Number of atoms of
Number of atoms of
Explanation of Solution
Number of moles of carbon = 10.0 mole
Number of moles of calcium = 10.0 mole
Since one mole of any substance is equal to the Avogadro number, i.e.,
Number of moles =
Put the values,
Number of atoms of
Number of moles of calcium = 10.0 mole
Number of atoms of
The number of atoms of 10.0 mole of carbon is equal to the number of atoms of 10.0 mole of calcium.
