The temperature in the room was 25.0 ºC. James was asked to transfer 4.50 mL of a liquid (density = 0.895 g/mL at 25.0 ºC) using a buret. He added the liquid into a 50-mL beaker weighing 25.789 g. He weighed the beaker with the liquid and found the combined mass was 29.413 g. His instructor asked him if he had made certain that there was no air bubble in the tip of the buret before he started dispensing the liquid from the buret. James said he was not sure because he had forgotten to look for the air bubble. Explain in detail, with calculations to support your explanation, how the instructor can check whether James really has 4.50 mL of the liquid.
