Answer 2

$\huge\mathfrak{Question :}$

Write the molecular formula of the following and give the ratio by mass of atoms present in water ?



$\huge\mathfrak\red{Answer :}$

=> Molecular Formula of Water is $H_{2}O$....

In Water; Hydrogen and Oxygen are present...

Also according to question we have to tell the ratio by mass of atoms present in Water.

1 molecule of Water consists of 2 atom of Hydrogen and 1 atom of Oxygen...

So, the ratio of Water i.e.

Hydrogen atom ratio to the Oxygen atom ratio is... 2 : 1

And Oxygen atom ratio to the Hydrogen atom is... 1 : 2
