Question

Poderia me ajudar galera?

Answer 1

Resposta:

C = 12 g/mol      O = 16 g/mol   N = 14 g/mol   Na = 23 g/mol    Cl =  35,5 g/mol

P = 31 g/mol      F = 56 g/mol   H = 1 g/mol     S = 32 g/mol

A) 12 + 3(16) = 60 g/mol

B) 3(1) + 31 + 4(16) = 98 g/mol

C) 1 + 12 + 14 = 27 g/mol

D) 2 + 32 + 4(16) = 98 g/mol

E) 23 + 35,5 = 58,5 g/mol

F) 56 + 2(17) = 90 g/mol
