|
number of neutrons in the nucleus |
|
number of protons in the nucleus |

212°F is how many °C?
100 |
|
\(135 {5 \over 9}\) |
|
0 |
|
-100 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
