1) How many moles of water does 6.02 x 1023 molecules
represent?

1.00 mol

Explanation:

Step 1: Given data

Molecules of water: 6.02 × 10²³ molecules

Step 2: Calculate the number of moles corresponding to 6.02 × 10²³ molecules of water

In order to convert molecules to moles, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.

6.02 × 10²³ molecules × 1 mol/6.02 × 10²³ molecules = 1.00 mol (we keep 3 significant figures)

b.

the accuracy of the data.
