On the right it says molecules H2o in questions 1 and 2​

For 1: 12.0 moles of water will contain number of molecules

For 2: The given amount of water molecules will be present in 5.41 moles of water.

Explanation:

According to the mole concept:

1 mole of a compound contains number of molecules

We are given:

Moles of water = 12.0 moles

Using above concept:

If 1 mole of a compound contains number of molecules

So, 12.0 moles of water will contain = number of molecules

Hence, 12.0 moles of water will contain number of molecules

We are given:

Molecules of water = molecules

Using above concept:

If number of molecules are present in 1 mole of a compound

So, number of molecules will be present in = moles of water

Hence, the given amount of water molecules will be present in 5.41 moles of water.
