1,C2H5OH
2,H2O
3,NH3
4,Co2
If you will answer accuratly so i will make you brainliest​

Answer 1

Answer:

(a) Molecular mas of Methanol (CH

3

OH)=1×C+3×H+1×O+1×H=(12+3+16+1)u=32u

(b) Molecular mass of Ethanol (C

2

H

5

OH)=2×C+5×H+1×O+1×H=(24+5+16+1)u=46u

Answer 2

1) C2H5OH= 2×12+5×1+16+1= 36u

2) H2O= 2×1+16= 18u

3) NH3= 14+3×1= 17u

4) CO2= 12+2×16= 44u
