The components of a 10.2 mg sample are sufficiently separated by a chromatographic column that is 2.5 cm in diameter and 50 cm long using a flow rate of 0.56 mL/min. To separate 205 mg of the sample with a similar separation of the components, what size column diameter and length should be used

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
