Answer: The number of molecules of [tex]H_2O[/tex] in 11.2 mol is [tex]69.253\times 10^{23}[/tex]
Explanation:
To calculate the number of molecules, we use mole concept.
According to the Mole concept,
1 mole of compound contains [tex]6.022\times 10^{23}[/tex] number of molecules.
So, 11.5 mole of [tex]H_2O[/tex] will contain [tex]11.2\times 6.022\times 10^{23}=69.253\times 10^{23}[/tex] number of molecules.
Hence, the number of molecules of [tex]H_2O[/tex] in 11.2 mol is [tex]69.253\times 10^{23}[/tex]
