45) George is making spaghetti for dinner. He places 4.01 kg of water in a pan and brings it to a boil.

Before adding the pasta, he adds 58 g of table salt to the water and again brings it to a boil. The
temperature of the salty, boiling water is _ _ _ _ __ _ _ _ _°
c.
It is a nice day at sea level so that pressure is 1.00 atm. Assume negligible evaporation of water.
Kb for water is 0.52°C/m. my book says the answer is: 100.26 how do i solve it?

On adding salt.....The boiling temperature increases.....

So ∆t= KB * molality
=O.52*(58/58)/4
= O.52*1/4
= 0.13
So increase is 100+.13=100.13°c
