Interpretation:
The relationship between mass and moles must be explained.
Concept introduction:
Both mass and mole represents quantity of a substance.
Mole is the amount of any substance in which

Answer to Problem 1TAI
Mass and mole are proportional to each other.
Explanation of Solution
If given mass of a substance is increased, then mole will also increase.
For example, 1 mole H2SO4 is 98 g. If 10 moles of H2SO4 is taken, then it will be 980 g.
Mole is the general unit for chemicals which can be used to compare the number of atoms, molecules, etc. as present in different samples.
For examples atoms in 12 g of C is
Thus, mass of two substances might be same but moles will be different. Accordingly, the number of atoms, molecules, etc. will be also different.
