Question

encontre as massas moleculares dos compostos:

a) C4H10 O b) al2 (SO4)3

c) CaNaP2O7 d) Ca Co3

Answer 1

a)C4H10
C  4.12 = 48
H  10.1 = 10
48 + 10 = 58u
Massa molecular do C4H10 = 58u

b) al2 (SO4)3
Al  2.27 = 54
S  3.32 = 96
O  3.16 = 48.4= 192
54 + 96 + 192 = 342u
Massa molecular do  al2 (SO4)3 = 342u

c)CaNaP2O7
Ca  1.40 = 40
Na  1.23 = 23
P    2.31 = 62
O    7.16 = 112
40 + 23 + 62 + 112 = 237
Massa molecular do CaNaP2O7 = 237u

d)Ca Co3
Ca  1.40 = 40
Co  3.59 = 177
40 + 177 = 217
Massa molecular do Ca Co3 = 217u
