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
# Elements and their masses

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](http://meta.codegolf.stackexchange.com/questions/1061/loopholes-that-are-forbidden-by-default), 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 [tag:code-golf], so the shortest submission (in bytes) wins.
