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 :
![n = \dfrac{560\ g}{60\ g/mol}\\\\n = 9.33\ mol](https://tex.z-dn.net/?f=n%20%3D%20%5Cdfrac%7B560%5C%20g%7D%7B60%5C%20g%2Fmol%7D%5C%5C%5C%5Cn%20%3D%209.33%5C%20mol)
Now, one mole of any compound contain
.
So, number of molecules in 9.33 moles of silicon dioxide is :
![M = 9.33\times 6.022\times 10^{23}\\\\M = 5.62\times 10^{24}\ molecules](https://tex.z-dn.net/?f=M%20%3D%209.33%5Ctimes%206.022%5Ctimes%2010%5E%7B23%7D%5C%5C%5C%5CM%20%3D%205.62%5Ctimes%2010%5E%7B24%7D%5C%20molecules)
Hence, this is the required solution.
True. The crust of the Earth has some permanent magnetization, and the Earth's core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore, a "magnet."
