Question

Calculate the number of molecules present in 34.20g of sugar cane

Answer 1

Answer

6.022 X 10^22. ( N / 10 )

Explanation:

Molecular Mass of sugar = 342g.

this means that 1 mole of sugar will have a mass of 342g .

By unitary method 1g will have 1  / 342 moles of sugar.

34.20g will have 0.1 moles of sugar.

1 mole has avagardo number of molecules(6.022 X 10^23)

0.1 mole will have 6.022 X 10^22.
