Question

count the atoms! 2c₃h₈o₂

Explanation:

Step1: Calculate carbon atoms

The sub - script of C is 3 and there are 2 molecules. So the number of C atoms is $2\times3 = 6$.

Step2: Calculate hydrogen atoms

The sub - script of H is 8 and there are 2 molecules. So the number of H atoms is $2\times8=16$.

Step3: Calculate oxygen atoms

The sub - script of O is 2 and there are 2 molecules. So the number of O atoms is $2\times2 = 4$.

Step4: Calculate total atoms

Add up the number of C, H and O atoms: $6 + 16+4=26$.

Answer:

26
