Asolution of ammonia and water contains 3.80•10^25 molecules of water and 5.50•10^24 molecules of ammonia. how many hydrogen atoms are in this solution? 1 molecule of water=1 oxygen and 2 hydrogen 1 molecule of ammonia= 1 nitrogen and 3 hydrogen show work

N H in H2O = 3.80×10²⁵ × = 7.60×10²⁵atoms of H

N H in NH3 = 5.50×10²⁴× = 1.65×10²⁵atoms of H

1.65×10²⁵+7.60×10²⁵= 9.25×10²⁵atoms of H

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
