Answer : The mass of NaCl needed would be, 86.1 grams.
Explanation :
Formula used for Elevation in boiling point :
or,
where,
= change in temperature =
= boiling point constant =
m = molality
i = Van't Hoff factor = 2 (for NaCl electrolyte)
= mass of solute (NaCl) = ?
= mass of solvent (water) = 1001 g
= molar mass of solute (NaCl) = 58.5 g/mol
Now put all the given values in the above formula, we get:
Therefore, the mass of NaCl needed would be, 86.1 grams.
