2. Home chefs add small amounts of salt to boiling water when making pasta to make it "cook faster" because they know the boiling point will be increased. (Kb= 0.512 C/m)

a. Calculate the mass of table salt (NaCl) needed to raise the temperature of 900 g of water by 1.0 C.

b. Will pasta cook faster with a couple pinches of added salt to boiling water? Why or why not? Explain your answer.

c. Estimate how much the boiling point changes by adding a couple pinches (estimate this mass in g) of salt to a pot of water. Justify your answer.
