Question

the ratio of hydrogen and oxygen in water is 2:1 let's work out the percentage of hydrogen and oxygen in water.











​

Answer 1

Step-by-step explanation:

To find the mass percent of hydrogen in water, take the molar mass of hydrogen in the water molecule, divide by the total molar mass of water, and multiply by 100. Dividing 2.016 by 18.016 gives you 0.1119. Multiply 0.1119 by 100 to get the answer: 11.19 percent.

Answer 2

Step-by-step explanation:

one molecule of water weight = 18 gram

oxygen in water = 1*16 g =16 g

hydrogen in water = 2*1 =2 g

percentage of oxygen in water = 16/18*100 = 88.89%

percentage of hydrogen in water = 2/18*100 = 11.11 %
