Worksheet: Mixed Problems Involving Mole and Mole Mass: Worksheet Mixed Problems Mole Mole And Mole Mass
This worksheet introduces the concepts of mole and mole mass, and provides practice in calculating the number of moles of a substance and the mass of a substance given the number of moles.
Calculating the Number of Moles, Worksheet mixed problems mole mole and mole mass
The mole is the SI unit of amount of substance. One mole of a substance contains exactly 6.022 × 10 23particles of that substance. The mole mass of a substance is the mass of one mole of that substance. The mole mass of a substance can be calculated by adding the atomic masses of all the atoms in the substance’s formula.
Calculating the Mass of a Substance
To calculate the mass of a substance given the number of moles, multiply the number of moles by the mole mass of the substance.
Relationship Between Mole and Molar Mass
The mole and the molar mass are related by the following equation:
Mass = Number of moles × Molar mass
Examples of Mixed Problems
The following table provides examples of mixed problems that involve both mole and mole mass calculations.
| Substance | Moles | Mass (g) | Molar Mass (g/mol) |
|---|---|---|---|
| Sodium chloride (NaCl) | 0.5 | 29.25 | 58.44 |
| Glucose (C6H12O6) | 0.25 | 45.0 | 180.16 |
