Question

Calculate how many moles of protons are there in 1 mole of H2O

Answer 1

Answer:

1 proton is present in H2O

Answer 2

Answer:

$6.022*10^{24}$ is your answer

Steps:

According to the Mole Concept, 1 mole of any substance consists of an Avogadro Number [$6.022*10^{23}$] of atoms/molecules.

In the answer, 'NA' means Avogadro's Constant

We'll Now Find Out Number of Protons in one Molecule Of Water

1 molecule of $H_{2}O$ consists 2 Hydrogen atoms and one Oxygen atom.

1 H atom has 1 proton. So 2 H atoms will have 2 protons

An oxygen atom consists of 8 protons

This is because number of protons = number of protons

So total number of protons in 1 molecule of $H_{2}O$ is 10 protons.

Now Total Number of Electrons in 1 mole of water

Now we can use simple Cross Multiplication method:

1 molecule --> 10 protons

NA molecules --> x protons

x =  10NA

x = 10 * $6.022*10^{23}$                                                             [$a^{m} * a^{n} = a^{m+n}$]

x = $6.022*10^{24}$ and your answer is here!!

Hope it helps,

Have a good Day
