The atomic mass of hydrogen is approximately 1.0079 amu. The atomic mass of an oxygen atom is approximately 15.9994 amu. What is the molecular mass of water? A.)34.02 amu B.)18.02 amu C.)17.02 amu D.)36.02 amu
1 answer:
Answer:
Explanation:
<u>Molecular mass of water: </u>
= H₂O
= 2(Atomic mass of H) + (Atomic mass of O)
= 2(1.0079) + 15.9994
= 2.0158 + 15.9994
= 18.02 amu
