There are more than 100 elements in the modern periodic table. You challenge is to output the rounded mass of an element with respect to the input given.
Input
- Input will contain an abbreviation of an element.
Input can be taken from any one of the following:
stdin- command-line arguments
- function arguments
Input will contain a one or two letter abbreviation of an element. The first character is always an uppercase letter and the second character, if any, will be a lowercase letter.
Output
- Output the mass of the element entered
- Output must be in the stdout or closest equivalent.
- Output may contain a trailing newline character

Yes. Your code only needs to deal with elements having atomic number 0-100 as seen in the table above.
Rules
- Standard loopholes are disallowed, as is fetching the data from built-ins
- You may write a full program, or a function.
Test Cases
O --> 16
Sn --> 119
H --> 1
Fm --> 257
Scoring
This is code-golf, so the shortest submission (in bytes) wins.
