Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

45. Calculate the percent by mass of each element in the following compounds:

a. HClO₃
b. UF₄
c. CaH₂
d. Ag₂S
e. NaHSO₃
f. MnO₂

This exercise involves determining the mass percentage of each element within various chemical compounds. To calculate the percent by mass of an element in a compound, use the formula:

\[ \text{Percent by mass} = \left( \frac{\text{Mass of the element in one mole of the compound}}{\text{Molar mass of the compound}} \right) \times 100\% \]

Each compound listed requires identifying its elemental components, calculating their respective molar masses, and computing the percentage of each element relative to the entire compound.
