Answer:
pls mark as brainliest!!!!!!
Explanation:
If you considering in smaller scale You can simply say that “There is One Hydrogen atom Binds with Cl atom”. But when we are using this chemicals in Labs.
We talking in Moles
Mole is a quantity defining unit. Which is larger than you couldn't Imagine. 1 mole of pebbles can covered whole surface of earth.
1Mole=6.022×1023
It means 1 mole of Hydrogen is containing 6.022×1023 atoms. Be aware “Be aware thats a Quantity defining factor” Then we can get actual ratio of chemical formula..
HCL “The chemical formula”
H : 1 “Above chemical formula containing 1 atom to binds with another species”
Cl : 1 “Clorin also same as Hydrogen”
Then, You can multiply Ratio of atom by Avagadro Constant which is we pre defined as 1 Mole.
For understand it simply This statement would be helpful.
1 mole containing, Avagadro number of atoms
Hope This would be helpful!
Answer:
the answer is going to be 3 because it asked how many atoms of hydrogen it never said how many number of atoms of hydrogen.
so,
HCl has 1 atom of hydrogen in ONE MOLE but there are 3 moles given so you multiply the atoms of hydrogen by 3 that is going to be your answer i.e. 3
