Question

determine a massa molecular
​

Answer 1

Resposta:

g) 318

h) 80

i) 746

j) 186

k)159

Explicação:

g) 54 + 72 + 192 = 318

Al = 27 x 2 = 54

C = 12 x 6 = 72

O = 16 x 12 = 192

h)  28 + 4 + 48 = 80

N = 14 x 2 = 28

H = 1 x 4 = 4

O = 16 x 3 = 48

i) 224 + 186 + 336 = 746

Fe = 56 x 4 = 224

P = 31 x 6 = 186

O = 16 x 21 = 336

j) 72 + 14 + 96 = 186

C = 12 x 6 = 72

H = 1 x 14 = 14

O = 16 x 6 = 96

k) 48 + 8 + 32 + 71 = 159

C = 12 x 4 = 48

H = 1 x 8 = 8

S = 32 x 1 = 32

Cl = 35,5 x 2 = 71
