Question

Calculate the number of moles present in 32 grams of sulphur dioxide​

Answer 1

Step-by-step explanation:

The molar mass of sulfur dioxide (SO2) can be calculated as follows:

Molar mass of Sulfur (S) = 32.07 g/mol

Molar mass of Oxygen (O) = 16.00 g/mol (x2, since there are two oxygen atoms in SO2)

Molar mass of SO2 = Molar mass of S + Molar mass of O (x2) = 32.07 g/mol + 16.00 g/mol * 2 = 64.07 g/mol

Now, plug the values into the formula:

Number of moles = 32 g / 64.07 g/mol ≈ 0.499 moles

So, there are approximately 0.499 moles of sulfur dioxide in 32 grams of it.
