Finding een molecular massStapsgewijze uitleg
1. Break down de molecule naar its elements
De molecule Ca(OH)123123123 consists van:
{ "ElementFrequency": "1", "Element": "calcium", "Count": "False" }{ "ElementFrequency": "123,123,123", "Element": "Zuurstof", "Count": "True" }{ "ElementFrequency": "123,123,123", "Element": "Waterstof", "Count": "True" }
| Chemisch element | Symbool | # van atoms |
| calcium | Ca | 1 |
| Zuurstof | O | 123123123 |
| Waterstof | H | 123123123 |
2. Identify de atomic mass van each element
De atomic mass is shown below each element op de periodic table.
Ca(OH)123123123 molecules consist van:
{ "Element": "calcium", "Symbol": "Ca", "Mass": "40,078" }{ "Element": "Zuurstof", "Symbol": "O", "Mass": "15,9994" }{ "Element": "Waterstof", "Symbol": "H", "Mass": "1,00794" }
| Chemisch element | Symbool | Atoommassa | # van atoms |
| calcium | Ca | 40,078 | 1 |
| Zuurstof | O | 15,9994 | 123123123 |
| Waterstof | H | 1,00794 | 123123123 |
3. Bereken de total atomic mass van each element in een molecule van Ca(OH)123123123
{Step3AllAtomsList:__TOK0__ → __TOK1__ u
|}
| Chemisch element | Symbool | Atoommassa | # van atoms | Totale atoommassa |
| calcium | Ca | 40,078 | 1 | 40,078 |
| Zuurstof | O | 15,9994 | 123123123 | 1969896094,1262 |
| Waterstof | H | 1,00794 | 123123123 | 124100720,59662001 |
4. Bereken de mass van de molecule Ca(OH)123123123
40,078+1969896094,1262+124100720,59662001=2093996854,80082
De averLeeftijd molecular mass van Ca(OH)123123123 is 2093996854,80082 u.

Every physical thing in de world is made up van matter. Whether het is de air wij breathe, de food wij eat, of de gas wij use naar heat ons homes, almost everything die exists is made up van matter, en alle matter is made up van molecules. Because van deze, understanding de properties van molecules can hulp us better understand de concepts die explain de world around us, such as waarom different materials behave as they do. Molecular mass is also een important concept voor anyone interested in pursuing een career in certain STEM fields.
