A gaseous mixture contains 0,256 g of hydrogen and 2.00 g of oxygen. The mole ration of hydrogen to oxygen in the mixture is (H=1.00; O=16,0)
-
A.
1:1 -
B.
2:1 -
C.
1:4 -
D.
8:1
Correct Answer: Option B
Explanation
Mole = (frac{Mass}{Molar Mas}) : (frac{Mass}{Molar Mass})
(frac{0.256}{2}) : (frac{2}{32}
0. 128 : 0.0625
(frac{0.128}{0.0625}) : (frac{0.0625}{0.0625})
2 : 1
