the molecular atomic mass difference between CH4 and C2H6 is..
Answers
Answer:
Molecular mass of CH4 = 16 u
vi) Molecular mass of C2H6= 2 x Atomic mass of C + 6 x Atomic mass of H
= 2 x 12 + 6 x 1
Molecular mass of C2H6 = 30 u
vii) Molecular mass of C2H4= 2 x Atomic mass of C + 4 x Atomic mass of H
= 2 x 12 + 4 x 1
Explanation:
Answer:
The total sum of the masses of the atoms or elements present in the molecule is termed as molecular mass.
i) Molecular mass of H2= 2 x Atomic mass of H
= 2 x 1
Molecular mass of H2 = 2 u
ii) Molecular mass of O2= 2 x Atomic mass of O
= 2 x 16
Molecular mass of O2= 32 u
iii) Molecular mass of Cl2= 2 x Atomic mass of Cl
= 2 x 35.5
Molecular mass of Cl2 = 71 u
iv) Molecular mass of CO2= Atomic mass of C + 2 x Atomic mass of O
= 12 + 2 x 16
Molecular mass of CO2 = 44 u
v) Molecular mass of CH4= Atomic mass of C + 4 x Atomic mass of H
= 12 + 4 x 1
Molecular mass of CH4 = 16 u
vi) Molecular mass of C2H6= 2 x Atomic mass of C + 6 x Atomic mass of H
= 2 x 12 + 6 x 1
Molecular mass of C2H6 = 30 u
vii) Molecular mass of C2H4= 2 x Atomic mass of C + 4 x Atomic mass of H
= 2 x 12 + 4 x 1
Molecular mass of C2H4 = 28 u
viii) Molecular mass of NH3= Atomic mass of N + 3 x Atomic mass of H
= 14 + 3 x 1
Molecular mass of NH3 = 17 u
ix) Molecular mass of CH3OH= Atomic mass of C + 4 x Atomic mass of H + 1 x Atomic mass of
= 12 + 4 x 1 + 16
Molecular mass of CH3OH = 32 u
