Definition1/12
0.630 g NaCl x (1 mol NaCl/58.44 g NaCl) = 0.0108 mol NaCl
525 g H2O x (1 kg/1000g) = 0.525 kg H2O
0.0108 mol NaCl/0.525 kg H2O = 0.0206 molality

What effect does adding a solute have on the boiling point of a solution
🔄 Click to see definition
Definition1/12
Adding a solute to a solution, or some liquid, causes the
boiling point to increase.
Think about water, sometimes people throw salt in their water
when they're boiling noodles. This causes the boiling point to
increase so the water is actually at a higher temperature (although
most of the time the amount of salt added isn't nearly enough to
cause any measurable change).
