science chemistryWhat is the percent composition by mass of the elements in the compound NaNO3?
Percent composition by element
| Element | Symbol | Mass Percent |
|---|---|---|
| Sodium | Na | 27.048% |
| Nitrogen | N | 16.480% |
| Oxygen | O | 56.472% |
Likewise, how do you calculate percent composition by mass?
Percent Composition
- Find the molar mass of all the elements in the compound ingramsper mole.
- Find the molecular mass of the entire compound.
- Divide the component's molar mass by the entiremolecularmass.
- You will now have a number between 0 and 1. Multiply it by100%to get percent composition.
Similarly, how do you find the percent composition of a mixture?
Mass percent is a method of expressingtheconcentration of a substance in a mixture or element inacompound. It is calculated as the mass of the component dividedbythe total mass of the mixture and then multiplied by 100toget the percent.
Percent composition by element
| Element | Symbol | Mass Percent |
|---|---|---|
| Silicon | Si | 46.743% |
| Oxygen | O | 53.257% |
