Question
**Chapter 8: Chemical Composition** **Problems** 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.
