How many moles of sulphur dioxide are made by 12.044 x 1021 molecules of the same?

To find the number of moles from the number of molecules, you can use Avogadro's number, which is 6.022 x 10^23 molecules/mole.

Step 1: Identify the given values. The given number of molecules is 12.044 x 10^21.

Step 2: Use Avogadro's number to convert molecules to moles. The formula to convert molecules to moles is:

Number of moles = Number of molecules / Avogadro's number

Step 3: Substitute the given values into the formula. Number of moles = (12.044 x 10^21) / (6.022 x 10^23)

Step 4: Perform the calculation. The result is approximately 0.02 moles of sulphur dioxide.
