Enter the average atomic mass (g/mol) and the reference standard (g/mol) into the Atomic Ratio Calculator. The calculator will evaluate and display the Atomic Ratio.
Atomic Ratio Formula
The following formula is used to calculate the Atomic Ratio.
AR = AAM / RS
- Where AR is the Atomic Ratio ( )
- AAM is the average atomic mass (g/mol)
- RS is the reference standard (g/mol)
To calculate the atomic ratio, divide the average atomic mass by the reference standard.
How to Calculate Atomic Ratio?
The following example problems outline how to calculate Atomic Ratio.
Example Problem #1:
- First, determine the average atomic mass (g/mol).
- The average atomic mass (g/mol) is given as: 3.67.
- Next, determine the reference standard (g/mol).
- The reference standard (g/mol) is provided as: 4.00.
- Finally, calculate the Atomic Ratio using the equation above:
AR = AAM / RS
The values given above are inserted into the equation below and the solution is calculated:
AR = 3.67 / 4.00 = .9175
Example Problem #2:
For this problem, the variables required are provided below:
average atomic mass (g/mol) = 7.89
reference standard (g/mol) = 9.00
Test your knowledge using the equation and check your answer with the calculator above.
AR = AAM / RS = ?
