Sagot :
Answer:
1. The subscript in the chemical formula indicates the relationship of atoms in the formula.
2. The Percent Composition is calculated from a molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of the entire compound.
3. The sum of percentages of each element in a compound is equal to Sum of Mass.
4. The percentage composition is obtained by using the equation Molecular Formula.
Explanation:
subscript
- is a character that is set slightly below or above the normal line of type, respectively. It is usually smaller than the rest of the text.
Percent Composition
- is the percent by mass of each element in a compound. It is calculated in a similar way to what was just indicated for the peanut butter. %by mass=mass of elementmass of compound×100%
Sum of Mass
- a massless particle is an elementary particle whose invariant mass is zero. The two known massless particles are both gauge bosons the photon (carrier of electromagnetism) and the gluon (carrier of the strong force).
Molecular Formula
- is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule.
