Example: Compound formula: MgCl_(2) Element: Mg If of Atoms: 1 Element: CI if of Atoms: 2 gram formula weight (g): 95.21 Compound Formula: HCI Element: H If of Atoms: square Element: CI II of Atoms: square : gram formula weight (g) square

To fill in the blanks for the compound formula :1. **Element: H** - Number of Atoms: 2. **Element: Cl** - Number of Atoms: 3. **Gram Formula Weight (g):** To calculate the gram formula weight of , we need to add the atomic weights of hydrogen (H) and chlorine (Cl). - Atomic weight of H = 1.01 g/mol - Atomic weight of Cl = 35.45 g/mol Therefore, the gram formula weight of is: So, the completed information for is:- Element: H - Number of Atoms: - Element: Cl - Number of Atoms: - Gram Formula Weight (g):
