Question

200ml of pure oxygen is subjected to electric discharge, 15%of oxygen is converted into ozone. the volume of ozonized oxygen is (a) 20ml (b) 30ml(c) 190ml (d) 80ml

Answer 1

THE ANSWER IS
B.) 30 ML

Answer 2

Given that,

Volume of oxygen = 200 ml

Percentage of oxygen converted to ozone = 15%

Volume of ozone formed is V.

We need to calculate the volume of ozonized oxygen

Using formula of volume

$\dfrac{\text{Volume of ozone}}{\text{Volume of oxygen}}=\text{Percentage of oxygen converted to ozone}$

$\dfrac{V}{200}=\dfrac{15}{100}$

$V=\dfrac{15\times200}{100}$

$V=30\ ml$

Hence, The volume of ozonized oxygen is 30 ml.
