CuSO_(4) .5H_(2)O_((g)) hArr CuSO_(4), 3H_(2)O_((s)) + 2H_(2) O_((g))

1.	CuSO_(4) .5H_(2)O_((g)) hArr CuSO_(4), 3H_(2)O_((s)) + 2H_(2) O_((g)) , K_(p) = 4 xx 10^(-4) atm^(2). If the vapour pressure of wateris38 torr then percentage of relative humidity is: (Assume all data at constant temperature)
Answer» 4 10 40 1 Solution :`K_(P)=P_(H_(2)O)^(2)` `= SQRT(K_(P))=2 XX 10^(-2)` ATM, `2 xx 10^(-2) xx 760` MM `% R.H=(P_(H_(2)O))/("vapour pressure of" H_(2)O) xx 100` `=(2 xx 10^(-2) xx 760)/(38) xx 100=40%`
