QUESTION
What is the chemical formula and molar mass for water?
Water is a covalently bonded compound with Hydrogen ##H## and Oxygen ##O## hence the chemical formula ##H_2O##.
The molar mass is determined by the sum of all elements' relative in the chemical formula, which is also known as the relative formula mass.
That being said, the molar mass of water is (1.01 x 2) 2 hydrogen atoms + (16) 1 oxygen atom = 18.02
