Question

Number of neutrons present in 64 grams of methane is equal to (assume methane contains C-12  and  H-1  isotopes)

Moderate
Solution

Number of fundamental particles in carbon = 6p + 6e + 6n

Number of fundamental particles in hydrogen = 1p + 1e

Number of fundamental particles in methane ( CH4 ) = 10p + 10e + 6n

GMW  of  CH416g  contains  6NA  neutrons                        64g  contains 'X' neutrons X=6416×6NA=24NA=14.4×1024 ;
