How many moles are present when there are 1.00.1026 molecules of water?

1.00×10^26=1000×10^23

1000×10^23/6.022×10^23=166.05×10^23 moles of water.

HOPE IT HELPS ☺️

PLEASE MARK AS BRAINLIEST

Explanation:

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above
