Question

calculate the molecule masses of CO2, CH4 , C2H6 , C2H4, NH3, CH3OH, H2 , O2 , Cl2
Please fast answer in only notebook pic okkkk with full solution please​

Answer 1

Explanation:

Note:- "mm" stands for molecular mass

mm of CO2=mm of c +2(sab mm of O)

=12+2×16

=12+32

=44

mm of CH4=mm of C+4(mm of H)

=12+4×1

=16

mm of C2H6 =2(mm of C )+ 6(mm of H)

=2×12+6

=30

mm of C2H4=2(mm of C )+4( mm of H )

=12×2+4

28

mm of NH3= mm of N +3(mm of H)

=14+3

=17

mm of CH3OH =mm of C+4(mm of H )+mm of O

=12+4+16

=32

mm of H2 =2(mm of H)

=2

mm of O2= 2(mm of O)

=2×16

=32

mm of Cl2=2(mm of Cl)

=2×35

=70

Note:- unit of molecular mass is kilogram per mol (kg mol^-1), but while solving numerical it is excluded
