Question

1120 ml of ozonised oxygen at stp weigh 1.76g. Calculate the volume of oxygen in ozonised oxygen

Answer 1

Answer:

From the given question we know that tge molecular mass of oxygen is 32 and that of ozone is 48.

If we let the volume of the oxygen to be x ml hence the volume of ozone will be 1120-x ml.

Thus at STP, weight of oxygen will be 32*x/22400 g.

Weight of 1120-x ml of ozone will be

48*(1120-x)/22400.

So, now equating as given in the question.

32*x/22400 + 48*(1120-x)/22400 = 1.76.

On solving we will get 16x = 14336.

So, x= 896 ml.

Answer 2

Explanation:

Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Wikipedia
