Which of these are equal to 6.02 x 1023 particles? 12.01 g carbon (c) 44.08 g of silicon dioxide (sio2) 16 g of ozone (o3) 16.04 g of carbon tetrahydride (ch4)

It is known that 1 mol of a substance is equal to 6.02x10^3 particles. This is called the Avogadro's number. From this knowledge, we convert the mass of the substances given above into units of moles by using the molar mass.

12.01 g C ( 1 mol / 12.01 g) = 1 mol 
44.08 g SiO2 ( 1 mol / 60.08 g ) = 0.73 mol
16 g of O3 (1 mol / 48 g) = 0.33 mol
16.04 g CH4 (1 mol / 16.05 g ) = 0.99 mol

So, the answers are carbon and carbon tetrahydride.

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.

The se-ci  bonds is more polar  than s-br bond
