Given :
560 gram of silicon dioxide.
To Find :
Number of moles of silicon dioxide in 560 gram.
Solution :
We know, molecular mass silicon dioxide is 60 gram/mol.
So, number of moles of silicon dioxide in 560 gram is :
[tex]n = \dfrac{560\ g}{60\ g/mol}\\\\n = 9.33\ mol[/tex]
Now, one mole of any compound contain [tex]6.022\times 10^{23}\ molecules[/tex].
So, number of molecules in 9.33 moles of silicon dioxide is :
[tex]M = 9.33\times 6.022\times 10^{23}\\\\M = 5.62\times 10^{24}\ molecules[/tex]
Hence, this is the required solution.
