Jawaban:

a. 6 HNO3

- atom H = 6

- atom N = 6

- atom O = 3 x 6 = 18

b. 8 KClO3

- atom K = 8

- atom Cl = 8

- atom O = 3 x 8 = 24

c. 12 KMnO4

- atom K = 12

- atom Mn = 12

- atom O = 4 x 12 = 48

d. 4 K2Cr2O7

- atom K = 2 x 4 = 8

- atom Cr = 2 x 4 = 8

- atom O = 7 x 4 = 28

e 5 Ba(OH)2

- atom Ba = 5

- atom O = 2 x 5 = 10

- atom H = 2 x 5 = 10

f. 2 Al(NO3)3

- atom Al = 2

- aton N = 3 x 2 = 6

- atom O = 3 x 3 x 2 = 18

g. 4 CuSO4.5H2O

- atom Cu = 4

- atom S = 4

- atom O = (4x4) + (5x2) = 26

- atom H = 2x5 = 10

h. 3 Ca3(PO4)2

- atom Ca = 3x3 = 9

- atom P = 2x3 = 6

- atom O = 4x2x3 = 24

i. 4 CaCO3

- atom Ca = 4

- atom C = 4

- atom O = 3x4 = 12

j. 2 Mg(NO3)2
