Suppose the boiling point of a solution of 1.15 g of an unknown molecular substance in 8.51 g of the solvent benzene is measured to be 58.5°C. The boil point of pure benzene is 55.0°C. The molal
boiling point elevation constant for benzene is 2.53 °C kg/mol. What is the change in boiling point
for the solution?
A) 58.5°C
B) 55.0°C
C) 3.5°C
D) - 3.5°C

In what way do investigations build scientific knowledge? the results of investigations lead to questions that cannot be tested. they reflect the opinions and social values of scientists, ensuring valid information. the results of investigations lead to new questions, which lead to new investigations. they are not influenced by the research of earlier scientists, so they are able to address gaps in understanding.i
