What is the molar mass of beryllium oxide (BeO)?

• A. 9.01 g/mol
• B. 40.08 g/mol
• C. 16.00 g/mol
• D. 25.01 g/mol

Answer: (D)

Verified step by step guidance

1. Identify the chemical formula of beryllium oxide, which is BeO, meaning it contains one atom of beryllium (Be) and one atom of oxygen (O).
2. Find the atomic masses of each element from the periodic table: beryllium (Be) has an atomic mass of approximately 9.01 g/mol, and oxygen (O) has an atomic mass of approximately 16.00 g/mol.
3. Calculate the molar mass of BeO by adding the atomic masses of beryllium and oxygen: \(\text{Molar mass of BeO} = \text{Atomic mass of Be} + \text{Atomic mass of O}\).
4. Substitute the values into the equation: \(\text{Molar mass of BeO} = 9.01\ \text{g/mol} + 16.00\ \text{g/mol}\).
5. Add the values to find the total molar mass of beryllium oxide, which represents the mass of one mole of BeO molecules.
