A solution is prepared by dissolving 300.0 g of KNO3 in a 1.0 L solution. Assuming the density of the solution is 1.20 g/mL, what is the mole fraction of the solution?

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the answer would be c

the answer is 75.0%.
