Fran wanted to find out how adding salt changes the boiling point of water. She placed 100 ml of water in each of 4 beakers. She then added a different amount of salt to each beaker. Finally, using a hot plate, Fran heated the beakers of water.

When the water began to boil, she measured the temperature using a thermometer. Her results are in the table below.

Solution # Dissolved
Salt (g) Boiling Point
(°C)
1 0 100.0
2 5.6 100.5
3 11.2 101.0
4 16.8 101.5
5 22.4 102.0

How much salt does it take to raise the boiling point of water by one degree?
A.
22.4 g
B.
16.8 g
C.
11.2 g
D.
5.6 g
