Question

560g of silicon dioxide to molecules of silicon dioxide. SiO2?

Answer 1

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 = (560\ g)/(60\ g/mol)\\\\n = 9.33\ mol`

Now, one mole of any compound contain
`6.022* 10^(23)\ molecules`.

So, number of molecules in 9.33 moles of silicon dioxide is :

`M = 9.33* 6.022* 10^(23)\\\\M = 5.62* 10^(24)\ molecules`

Hence, this is the required solution.
