Which contains larger percentage of oxygen, `H_(2)O or N_(2)O_(3)?`

Text Solution

AI Generated Solution

To determine which compound contains a larger percentage of oxygen, we will calculate the mass percentage of oxygen in both \( H_2O \) (water) and \( N_2O_3 \) (dinitrogen trioxide). ### Step 1: Calculate the molar mass of \( H_2O \) - The molar mass of \( H_2O \) is calculated as follows: - There are 2 hydrogen atoms, each with an atomic mass of 1 g/mol. - There is 1 oxygen atom with an atomic mass of 16 g/mol. \[ ...

The strength of H_(2)O_(2) is expressed in several ways like molarity, normality,% (w/V), volume strength, etc. The strength of "10 V" means 1 volume of H_(2)O_(2) on decomposition gives 10 volumes of oxygen at 1 atm and 273 K or 1 litre of H_(2)O_(2) gives 10 litre of O_(2) at 1 atm and 273 K The decomposition of H_(2)O_(2) is shown as under : H_(2)O_(2)(aq) to H_(2)O(l)+(1)/(2)O_(2)(g) H_(2)O_(2) can acts as oxidising as well as reducing agent. As oxidizing agent H_(2)O_(2) is converted into H_(2)O and as reducing agent H_(2)O_(2) is converted into O_(2) . For both cases its n-factor is 2. :.
