Question

count the atoms! 2ga(oh)3

Explanation:

Step1: Analyze Ga atoms

There is a coefficient of 2 in front of the formula $2Ga(OH)_3$. So the number of Ga atoms is $2\times1 = 2$.

Step2: Analyze O atoms

Inside the parentheses, the sub - script of O is 1 and there is a sub - script of 3 outside the parentheses, and a coefficient of 2 in front of the whole formula. So the number of O atoms is $2\times3\times1=6$.

Step3: Analyze H atoms

Similar to O atoms, the sub - script of H is 1, sub - script outside parentheses is 3 and coefficient in front is 2. So the number of H atoms is $2\times3\times1 = 6$.

Step4: Calculate total atoms

Total atoms = number of Ga atoms+number of O atoms + number of H atoms. So total atoms $=2 + 6+6=14$.

Answer:

14
