Question

which of the following have larger number of atom1) 1 mole of NH3 2)2 mole of HCL

Answer 1

1 mole of NH3 is the correct answer.

Answer 2

heya mate:-) :-) :-) :-) :-) :-)

here's ur answer

Calculation of number of hydrogen atoms present in 2 moles of HCl

1 mole of HCl contains 6.023X1023 molecules of HCl

2 moles of HCl contains 2 X 6.023X1023= 12.046X1023 molecules of HCl

1 molecule of HCl contains 1 hydrogen atom

12.046X1023 molecules of HCl contains12.046X1023 hydrogen atoms

Calculation of number of hydrogen atoms present in 1 mole of NH3

1 mole NH3 Contains 6.023X1023 molecules of NH3

1 molecule of NH3 contains 3 atoms of hydrogen

6.023X1023 molecules of NH3 contains 3X 6.023X1023 atoms of hydrogen

= 18.069 X1023 atoms of hydrogen

Number of hydrogen atoms present in 2 moles of HCl = 12.046X1023

Number of hydrogen atoms present in 1 mole of NH3 = 18.069 X1023

Therefore numbers of hydrogen atoms are more in 1 mole of NH3.

hope it helps
