How many mL of perhydrol is requried to produce sufficient oxygen which can be used to completely convert 2 L of `SO_(2)` gas of `SO_(3)` gas?

Options

A. 10 mL
B. 5 mL
C. 20 mL
D. 30 mL

Answer

A

Explanation

`underset(2L)(SO_(2)(g))+underset(1L)((1)/(2))O_(2)(g)to underset(2L)(SO_(3))(g)`
1L `O_(2)` is required for 2L `SO_(2)` to convert it into `SO_(3)`.
`undersetunderset((68)/(227)g)(68g)(2H_(2)O_(2))to undersetunderset(1L)(22.7)L(2H_(2)O)+O_(2)`
Percentage strength of `H_(2)O_(2)=30%`
i.e., `30g" "H_(2)O_(2)` in 100 mL solution of
`H_(2)O_(2)(68)/(22.7)g" "H_(2)O_(2)` in
`(100xx(1)/(30)xx(68)/(22.7))mL` solution of
`H_(2)O_(2)=9.98mL" "H_(2)O_(2)` or 10 mL `H_(2)O_(2)`.
