• NH3,
• CH3OH,
• C2H2OH

Pls....answer.....I will mark the best as brainliest.....

Answer 1

Hey!!

your answer is ----

MOLECULAR MASS OF

• H2 = 1 + 1 = 2

• O2 = 16 + 16 = 32

• Cl2 = 35.5 + 35.5 = 71

• CO2 = 12 + 2×16 = 12 + 32 = 44

• CH4 = 12 + 4×1 = 12+ 4 = 16

• C2H6 = 2×12 + 1×6 = 24 + 6 = 30

• C2H4 = 2×12+1×4 = 24+4 = 28

• NH3 = 14+3×1 = 14+3 = 17

• CH3OH = 12+1×3+16+1 = 15+17 = 32

• C2H2OH = 2×12+2×1+16+1 = 24+19=43
