which is the molar mass of h2o?\n10.02 g/mol\n16.00 g/mol\n17.01 g/mol\n18.02 g/mol
which is the molar mass of h2o?\n10.02 g/mol\n16.00 g/mol\n17.01 g/mol\n18.02 g/mol
Answer
Explanation:
Step1: Determine molar mass of H
The molar mass of hydrogen (H) is approximately 1.01 g/mol. In H₂O, there are 2 hydrogen atoms. So the total mass contributed by hydrogen is $2\times1.01\ g/mol = 2.02\ g/mol$.
Step2: Determine molar mass of O
The molar mass of oxygen (O) is approximately 16.00 g/mol. There is 1 oxygen atom in H₂O.
Step3: Calculate molar mass of H₂O
Add the mass of hydrogen and oxygen in H₂O. So the molar mass of H₂O is $2.02\ g/mol+ 16.00\ g/mol=18.02\ g/mol$.
Answer:
18.02 g/mol
