The number of molecules contained in sulfur oxide (6) weighing 8 g is equal to the number of molecules

The number of molecules contained in sulfur oxide (6) weighing 8 g is equal to the number of molecules in sulfur oxide (4) with the chemical amount: A) 1 mol B) 10 mol C) 0.1 mol D) 0.5 mol

The number of molecules in 1 mole of any substance is the same and equal to the Avogadro number Na – 6.02 * 10 ^ 23.

Let’s find the amount of a substance (chemical amount) of sulfur oxide (VI).

n (SO3) = m (SO3) / M (SO3) = 8/80 = 0.1 mol

N (SO3) = 0.1 * 6.02 * 10 ^ 23 = 6.02 * 10 ^ 22

0.1 mol SO2 will contain the same number of molecules (6.02 * 10 ^ 22) as 0.1 mol SO3.

Correct answer: B.
