What is equal to the number of particles in 36 grams of carbon-12?

3 moles

1:3 molar volume

3:1 mole ratio

3:1 molar mass

3 moles

Explanation:

To solve this problem we will use the Avogadro numbers.

The number 6.022*10²³ is called Avogadro number and it is the number of atoms, ions or molecules in one mole of substance. According to this,

1.008 g of hydrogen = 1 mole = 6.022*10²³ atoms.

18 g water = 1 mole = 6.022*10²³ molecules

we are given 36 g of C-12. So,

12 g of C-12 = 1 mole

24 g of C-12 = 2 mole

36 g of C-12 = 3 mole

So 3 moles of C-12 equals to the number of particles in 36 g of C-12.
