how many elements are present in 4h₂o?

Explanation:

Step1: Identify elements in cellulose formula

In $C_{6}H_{7}O_{2}(OH)_{3}$, elements are C (carbon), H (hydrogen), O (oxygen). So there are 3 elements.

Step2: Identify elements in $4H_{2}O$ formula

In $4H_{2}O$, elements are H (hydrogen) and O (oxygen). So there are 2 elements.
