The density of 2m-aqueous `H_(2)O_(2)` solution is `1.068g//ml`. Which of the following is/are correct concentration(s) of this solution, in different units?

Options

A. Molarity = 2M
B. Volume strength = '22.7 V'
C. `%(w//v)=6.8`
D. Mole-fraction of water = `(250)/(259)`

Answer

A, B, C, D

Explanation

2m aqueous solution of `H_(2)O_(2)`
Suppose of `H_(2)O` is 1000g
`n_(H_(2)O_(2))=2" "W_(H_(2)O_(2))=2xx34=68g`
`W_("sol")=1000+68=1068`
`V_("sol")=(1068)/(1.068)=1000ml`
`(A) M = (n_(H_(2)O_(2)))/(v_("sol")(L))=(2)/(1)=2`
`(B) v = M xx 11.35 =22.7`
`(C ) M=(%w//vxx10)/(Gmm)implies % w//v=6.8`
`(D) X_(H_(2)O_(2))=(n_(H_(2)O))/(n_(H_(2)O)+n_(H_(2)O_(2)))=(1000//18)/((1000)/(18)+2)=(250)/(259)`
