Question

1. 5c₃h₅(oh)₃ c= h= o=

Explanation:

Step1: Determine the number of atoms of each element in one molecule of $C_3H_5(OH)_3$

In $C_3H_5(OH)_3$, the number of carbon (C) atoms is 3, the number of hydrogen (H) atoms is $5 + 3=8$, and the number of oxygen (O) atoms is 3.

Step2: Multiply by the coefficient 5

For carbon: $5\times3 = 15$.
For hydrogen: $5\times8=40$.
For oxygen: $5\times3 = 15$.

Answer:

$C = 15$, $H = 40$, $O = 15$
