# State the no of neutrons in 1.6 g of methane ______?

Dear Student,
molar mass = 16 gm
16 gm = 1 mole
1,6 gm= $\frac{1}{16}×1.6$ =0.1moles
1 mole of methane has 6.023$×{10}^{23}$ molecules

so  0.1 moles have  molecules
1 molecule = 6 neutrons  (1 C has 6 neutrons , H has no neutrons)
so $6.023×{10}^{22}$ molecules have =$6×6.023×{10}^{22}$  =
Regards!

MW of methane = 16 g/mole   So, no of moles of methane in 1.6 g = 1.6 /16 g/mole = 0.1 Since, in 1 mole methane there are 6.022 x 1023 molecules of methane,    so, in 0.1 mole there will be 0.1 x 6.022 x 1023 molecules of methane   In 1 methane molecule there are 10 electrons (6 + 4)   total electrons in 0.1 mole or 1.6 g = 10 x 0.1 x 6.022 x 1023  = 6.022 x 1023

NEUTRONS = 6.022 x 1023

i think  there is a mistake in the question pls check your question again.
