this is the chemical formula for zinc bromate: zn(bro₃)₂. calculate the mass percent of oxygen in zinc…

Explanation:

Step1: Calculate molar mass of each element

• Molar mass of (Zn): (M_{Zn}=65.38\space g/mol)
• Molar mass of (Br): There are (2) (Br) atoms. (M_{Br}=2\times79.904 = 159.808\space g/mol)
• Molar mass of (O): There are (6) (O) atoms. (M_{O}=6\times16.00=96.00\space g/mol)

Step2: Calculate molar mass of (Zn(BrO_{3})_{2})

(M = M_{Zn}+M_{Br}+M_{O}=65.38 + 159.808+96.00=321.188\space g/mol)

Step3: Calculate mass percent of (O)

Mass percent formula: (\text{Mass}%=\frac{\text{Mass of component}}{\text{Total mass}}\times100) (\text{Mass}%\text{ of }O=\frac{96.00}{321.188}\times 100\approx29.9%)
