Question

Calculate the molecular mass of the following in u a. NH3 b. CH3 COOH c. C2H5OH

Answer 1

Explanation:

N= 22

h= 1

NH3= 22+3(1)

=25

2)C= 12

H=1

O=16

12+3(1) + 12+16(2)+1

= 60

3) C=12

H= 1

2(12)+5(1)+16+1

=46

Answer 2

Answer:

a. The molecular mass of NH3 is 17.031g/mol

b. The molecular mass of CH3COOH is 60.052g/mol

c. The molecular mass of C2H5oh is 46.07g/mol

hope this helps you!!

thanks!
