Hi
Can someone please help me to solve this with steps?
Thank you.

1 mole of H2O –> 1+1+16=18g (molar mass) –> 6 x 1023 H2O molecules –> 2x6x1023 H atoms + 6×1023 O atoms
12.6 moles of H2O –> 12.6 x 2 x 6 x 1023 H atoms = 151.2 x 1023 = 1.512 x 1025 H atoms#
Hope you have the answer to counter check in case I got it wrong. Too many years ago. I opened my DC’s textbook to double check Avogadro’s constant last night… 🙂 photo attached for info only.
