caustic soda cantains sodium ,oxygen & hydrogen in the ratio 23:16:1 find the %OF OXYGEN IN CAUSTIC SODA WHAT WEIGHT OF CAUSTIC SODA WILL CANTAIN 10g OF HYDROGEN
Given: caustic soda contains sodium, oxygen & hydrogen in the ratio 23:16:1, so,
Percentage of Oxygen in Caustic Soda = 
Now, Let total weight of Caustic soda = x g
Weight of Hydrogen = 
Since,
x/40 g of Hydrogen contained in x g Caustic soda, so,
10 g of Hydrogen will contain in 
Caustic soda.
Hence, Percentage of Oxygen in Caustic soda is 40% and 400 g Caustic soda will contain 10 g of Hydrogen.
