FAQs on Relative Formula Mass Video Lecture - Chemistry for GCSE/IGCSE - Year 11

1. What is relative formula mass?
Ans. Relative formula mass is the sum of the atomic masses of all the atoms in a formula unit of a compound, expressed in atomic mass units (u).
2. How is relative formula mass calculated?
Ans. To calculate the relative formula mass of a compound, you need to multiply the atomic mass of each element in the compound by the number of atoms of that element present, and then add up all the results.
3. Why is relative formula mass important in chemistry?
Ans. Relative formula mass is important in chemistry because it helps in determining the proportion of elements present in a compound, which is crucial for understanding the chemical properties and reactions of the compound.
4. How is relative formula mass different from molecular mass?
Ans. Relative formula mass is the sum of the atomic masses of all the atoms in a formula unit of a compound, while molecular mass is the sum of the atomic masses of all the atoms in a molecule of a compound.
5. Can relative formula mass be used to predict chemical behavior?
Ans. Yes, relative formula mass can be used to predict chemical behavior as it provides information about the composition of a compound, which in turn influences its properties and reactions with other substances.
