Question

Which formula can be used to calculate the molar mass of water (H2O)?

2 × molar mass of H + 2 × molar mass of O

molar mass of H + 2 × molar mass of O

2 × molar mass of H + molar mass of O

molar mass of H + molar mass of O

Answer 1

2 × molar mass of H + molar mass of O

Step-by-step explanation:

Answer 2

2 x molar mass of H + molar mass of O
In simpler terms as its H2O
There are two atoms of hydrogen and 1 atom of oxygen . Using simple math this would be (1x2)+16 =18
The mass of hydrogen is 1 and the mass of oxygen is 16 so adding it together taking into account there is 2 atoms of hydrogen, would be 18
