Chemistry numericals calculator
Pick an ISC Chemistry formula - colligative properties, molarity, the Nernst equation, Kohlrausch’s law, rate constants and half-lives - fill in what you know with units, and get every letter you left empty. R, F and other constants take ISC’s values.
Answer
- n
- 0.5 mol
Working
Number of moles
n = w/M
| Letter | Value | In SI units | |
|---|---|---|---|
| w | 9 g | given | 0.009 kg |
| M | 18 | given | 0.018 kg / mol |
Every value is turned into SI units, the formula is solved for what was left empty, and the answer is given back in the usual unit.
