Question

how many electrons protons and neutrons are present in 1.8gm of NH4+?​

Answer 1

Answer:

1 molecule of NH4+ has 11 protons. Hence 1 mole NH4+ will have 11 mole protons.

Moles of NH4+ = 1.8/18 = 0.1.

Hence number of protons = 0.1 x 11 x NA = 1.1 NA.

Correct answer is (3).

molar mass(nh4+)= 18 gm

no. of protons in one nh4+ ion=7+4=11

no. of protons in 1 mole NH4+= 11*NA

no. of moles=given mass /molar mass=1.8/18=0.1

no. of protons in 0.1 mole NH4+=0.1*11*NA=1.1NA

4 is the answer
