The student who performed this experiment in the question above wrote the following discussion: "the gas sample is known to contain compounds of only hydrogen and carbon. the measured molecular weight of the flammable gas is closest propane (44.1 g/mole), but lies between propane and butane (58.1 g/mole). i therefore conclude that there is a possibility that the sample is not a pure compound but rather is equal parts propane and butane." this seems qualitatively reasonable except her hypothesis that the gas is a 1: 1 mixture is not supported by the data. what gas mixture is suggested by the molecular weight measured in the experiment? give the percent propane in the mixture in the box provided. do not enter the percent symbol. enter your answer with the correct number of significant digits.

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
