Answer
a. 178.3 g/mol
b. 371.3 g/mol
c. 136.1 g/mol
d. 365.4 g/mol
Work Step by Step
a. ( 1.008 $\times$ 18 )+ ( 12.01 $\times$ 12 )+ ( 16.00 $\times$ 1 )= 178.3 g/mol
b. ( 195.1 $\times$ 1 )+ ( 1.008 $\times$ 12 )+ ( 12.01 $\times$ 6 )+ ( 14.01 $\times$ 2 )+ ( 16.00 $\times$ 4 )= 371.3 g/mol
c. ( 40.08 $\times$ 1 )+ ( 16.00 $\times$ 4 )+ ( 32.06 $\times$ 1 )= 136.1 g/mol
d. ( 1.008 $\times$ 19 )+ ( 12.01 $\times$ 16 )+ ( 14.01 $\times$ 3 )+ ( 16.0 $\times$ 5 )+ ( 32.06 $\times$ 1 )= 365.4 g/mol
