Answer:
6 atoms
Step-by-step explanation:
Hey there!
To find out how many atoms are in this compound, we have to add up all of the atoms
2H means there are 2 atoms
Then we have Cl which is 1 more atoms
Last, we have O₃ which gives us 3 atoms
Now we do basic math:
2 + 1 + 3 = 6
So there are 6 atoms in this compound
