Question
mID 64383283 Signed in as Au Correct rates how Dalton's atomic theory explains the law of definite proportions in any sample of water no matter how large or smal, the ratio Your answer to oxygen atoms will always be 2:1 because that is the ratio within one single molecule How many atoms of hydogen (H are present in 200 molecules of ammonia (NH3? Express your answer numerically. Submi Hints My Answers Give Up ReviewPart Correct since each ammonia molecule contains three atoms, there will always be three times as many Hatems as there are NHa molecules hydrogen Part C A solution of ammonia and watercontains 390-10 water molecules and 8.20. 1024 ammonia molecules How many total hydrogen atoms are in this solution?

Molecules of NH3= 3.95*1025
NH3----------à N +3/2H2
1 mole of NH3 containd 1.5 atoms of hydrogen
6.023*1023 molecules of NH3 containd 6.023*1023* 1.5 = 9.034*1023 atoms of hydrogen
3.95*1025 molecules of NH3 contains 9,034*1023*3.95*1023/6.023*1023 = 5.925*1025 atoms
H2O--à 2H + 1/2O2
1mole = 6.023*1023 molecules of H2O contains 2*6.023*1023 atoms of hydrogen
20*1024 molecules of H2O contains =20*2*1024 atoms of hydrogen= 40*1024 atoms of hydrogen =4*1025 atoms of hydrogen.
Total atoms of hydrogen= (5.925+4)*1025 atoms =9.925*1024 atoms
