Question

How many molecules of sulfur dioxide are present in 1.60 moles of sulfur dioxide

Answer 1

To determine the number of molecules of sulfur dioxide present in 1.60 moles of sulfur dioxide, you can use Avogadro's number. Multiply the number of moles by Avogadro's number to calculate the number of molecules.

Step-by-step explanation:

To determine the number of molecules of sulfur dioxide present in 1.60 moles of sulfur dioxide, we need to use Avogadro's number. Avogadro's number, which is approximately 6.022 × 10^23, represents the number of molecules or atoms in one mole of a substance.

Given that we have 1.60 moles of sulfur dioxide, we can multiply this by Avogadro's number to calculate the number of molecules. So, the number of molecules of sulfur dioxide is:

1.60 moles of sulfur dioxide × (6.022 × 10^23 molecules per mole) = 9.6352 × 10^23 molecules of sulfur dioxide.

Answer 2

For this question, you must know that there are 6.022e23 atoms/molecules per mole of any substance (this is Avogadro's number). Therefore, your answer is 6.022e23 * 1.60 = 9.64e23 molecules of sulfur dioxide. (the "e" represents "times ten to the power of ___ ")
