Question

What is the molar mass of water??

Answer 1

Each water molecule contains two hydrogen atoms (`M = "1.0079 g/mol"`) and one oxygen atom (`M = "15.999 g/mol"`). Therefore, the molar mass is:

`M_(H_2O) = 2 xx "1.0079 g/mol" + "15.999 g/mol" = "18.015 g/mol"`

And this is one you should know because you'll use it very often...
