In an experiment, a student was asked to measure the densities of liquid acetone and metallic chromium. He was given a pycnometer which weighed 26.880 g empty. When filled with water and stoppered, the mass was recorded as 54.992g at 28C. The pycnometer was cleaned and filled with acetone. The mass was 49.137 g. Again, the flask was cleaned and dried. Into it were added some chunks of chromium and the total was found to weight 78.666 g. Leaving the chromium in the pycnometer, it was then filled with acetone. The flask, metal and acetone were found to weigh 95.199 g. From this data, calculate the density of acetone and the density of chromium (show all your calculations).
