Calculatethe osmoticpressureof 6%sucrose(C_(12) H_(22)O_(11))solutionat 300 K (R 8. 314 J mol^(-1) K^(-1))

Answer»


SOLUTION :Given : W= Amountof sucrose=`6g = 6.0 XX 10^(3) kg `
M= Molecularweightof sucrose`=(C_(12) H_(22) O_(11))`
`=(12 xx 12 + 22 xx 1+ 11 xx 16)`
`=342 "mol"^(-1)`
`= 342 xx 10^(-3) kg "mol"^(-1)`
n= Number of themoles ofsucrose `= (W)/(M)= (6.0 xx 10^(-3))/(352 xx 10^(-3))`
`=0.01754 "mol"`
V= Volumeof the solution=100ml = 0.1 `dm^(3)`
`=0.1 xx 10^(-3)m^(3)`
T=Temperatureof thesolution=300 K
`R= 8.314 J "mol"^(-1) K^(-1)`
