1)
temperature T = 20 + 273 = 293 K
Osmatic pressure P = M x S x T
47 = M x 0.0821 x 293
M = 1.95
final concentration of sea water = 1.95 M
2)
final = 1.95 M
initial = 1.10 M
for 1 L sea water :
Ci / (1 - W) = Cf
1.10 / 1 - W = 1.95
W = 0.437 L
for fresh water 15.4 L required = 15.4 / 0.437
= 35.3 L
