Hello.
1) A) From the definition of mole, we can conclude that 1 mol of H2O contains 6.022×1023 molecules of water (simply Avogadro’s number of molecules). How many moles of water, H2O, contains 2.0×1022 molecules of water? Express the quantity in moles to two significant figures. I put .03 but it was wrong.
