Isotope Mass Formula
The following formula is used to calculate the Isotope Mass.
IM = TM * PM/100
- Where IM is the Isotope Mass (g)
- TM is the total substance mass (g)
- PM is the isotopes percent mass of the total mass (%)
How to Calculate Isotope Mass?
The following example problems outline how to calculate Isotope Mass.
Example Problem #1:
- First, determine the total substance mass (g).
- The total substance mass (g) is given as: 89.
- Next, determine the isotopes percent mass of the total mass (%).
- The isotopes percent mass of the total mass (%) is provided as: 30.
- Finally, calculate the Isotope Mass using the equation above:
IM = TM * PM/100
The values given above are inserted into the equation below and the solution is calculated:
IM = 89 * 30/100 = 26.7 (g)
Example Problem #2:
For this problem, the variables needed are provided below:
total substance mass (g) = 90
isotopes percent mass of the total mass (%) = 24
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
IM = TM * PM/100 = ?
