A gaseous mixture contains 0,256 g of hydrogen and 2.00 g of oxygen. The mole ratio 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
B. 2:1
Explanation
Mole = Mass/MolarMas : Mass/MolarMass
0.256/2 : 2/32
0.128:0.0625
Divide through by the smallest.
(0.128/0.0625 : 0.0625/0.0625
2 : 1
