NA CNTP um mol de 1 gás equivale a 22,4L

Massa Molar do CO = 12 + 16 = 28g/mol

Agora usamos regra de 3.

1 mol de CO ----------------- 28g
x mols de CO ----------------10g

28x=10

x=10/28

x=0,357 ~= 0,36 mols.

************************************

1 mol ------------------------- 22,4 L
0,36mols ------------------------x


x=22,4*0,36

********************************************************
x= 8,064 ~= 8 Litros de Volume (aproximadamente)
