Interpretation: To calculate the molar mass of the given substance.
Concept Introduction: Molar mass is defined as the smallest unit of the compound. It is the
Answer to Problem 114A
205.92 g/mol
Explanation of Solution
Given that the mass of lead atom is 17.16 times more than that of the carbon-12
The mass of Carbon-12 atom is 12 g/mol
Since, the mass of lead is 17.6 times greater than that of the carbon-12 atom. The mass of lead will be
Therefore, the molar mass of the isotope of lead will be 205.92 g/mol.
The molar mass is nothing but the mass of one mole of that element. This molar mass is also used for calculation of concentration terms like molality, molarity and also for the calculation of number of moles.
