Question

2 H20molecules of H2OH (hydrogen)O (oxygen)

Answer 1

Molecules of water = 1.204 x 10^24

Hydrogen atoms = 2.408 x 10^24

Oxygen atoms = 1.204 x 10^24

Explanation:

`\begin{gathered} \text{ Firstly, we n}eed\text{ to establish a balanced equation} \\ 2H_{2_{_{}}}O\text{ }\rightarrow2H_2+O_2 \end{gathered}`

From the equation,

We have 2 moles of water

2 moles of hydrogen

1 mole of oxygen

Mole = no of molecules / Avogadro's number

No of molecules = mole x Avogadro's number

For water

No of molecules = 2 * 6.02 x 10^23

No of molecues = 12.04 x 10^23

No of molecules = 1,204 x 10^24

Hence, water has 1.204 x 10^24 molecules

From the chemical equation,

We have two moles of Hydrogen

Hence, the number of hydrogen atoms can be calculated as'

2 * 1.204 x 10^24

2.408 x 10^24

Hence, we have 2.408 x 10^24 of Hydrogen atoms in 2 moles of water
