4 moles of water
We are given;
Molecules of water as 2.41x10^24 molecules
To get the number of moles we divide the number of molecules with the Avogadro's constant.
Number of moles of water = (2.41x10^24 molecules)÷(6.022×10^23)
Therefore, 2.41x10^24 molecules of water are equal to 4 moles of water.
