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
