Answer:
0.808 M
Explanation:
Using Raoult's Law
where:
= vapor pressure of sea water( solution) = 23.09 mmHg
= vapor pressure of pure water (solute) = 23.76 mmHg
= mole fraction of water
∴
------ equation (1)
------ equation (2)
where; number of moles of sea water
number of moles of pure water
equating above equation 1 and 2; we have :
NOW, Molarity =
As we assume that the sea water contains only NaCl, if NaCl dissociates to Na⁺ and Cl⁻; we have
