I hope this helps in some way. I forgot to mention that the question states they want to find THE NUMBER OF MOLES for H2O. Yherefore, you would want mol of H2O on top.
2.167*10^22 atoms of hydrogen
Here goes the question with no exact answer, lol <3
Scientists tell us that the observable universe is about 90 light years but then I wonder how they calculated that because the universe is immense!
I'm sorry but I can't go deeper into explaining as that's a tough question.
Answer:
Factors that cause population growth include increased food production, improved health care services, immigration and high birth rate.

Hope this helps!
