The volume of perhydrol which on decomposition gives `1L` of `O_(2)` at STP is

20gm of CaCO_(3) on decomposition gives CO_(2) at STP:

The volume of 8 g O_(2) at STP is

The volume is O_(2) obtianed by the decomposition of 4 litres of O_(3) at STP is

At STP 1g Ca CO_(3) on decomposition gives CO_(2)

Under similar conditions of temperature and pressure,2 volumes of ozone (O_(3)) on decomposition give 3 volumes oxygen (O_(2)) . 20 mL of the gaseous mixture when heated and then cooled expands to 21 mL. Find the percentage volume ozone in the gaseous mixture.

17g of H_(2)O_(2) is present in 100ml of an aqueous solution. 10ml of this solution on decomposition at S.T.P will produce ml of O_(2) at S.T.P
