Question

D. Calculate the molecular mass of the
following in u.
a. NH3, b. CH3,COOH c. C3,H5,OH​

Answer 1

Answer:

NH3:

Explanation:

NH3:14+3(1)=17

CH3COOH:12+3(1)+12+16+16+1=60

C3H5OH:12+5(1)+16+1=34

Answer 2

Explanation:

Molecular mass of

NH3=14+3×1

=14+3

=17 u

Molecular mass of CH3COOH=12+1×3+12+16+16+1

=12+3+12+16+16+1

=60 u

Molecular mass of

C3H5OH=12×3+5×1+16+1

=36+5+17

=58 u
