A chemistry graduate student is studying the rate of this reaction: 2H3PO4 (aq) ---> P2O5 (aq) + 3H2O (aq)He fills a reaction vessel with and measures its concentration as the reaction proceeds: time (seconds) [H3PO4]0 0.03M1 0.018M2 0.011M3 0.0067M4 0.0041MUse this data to answer the following questions. Write the rate law of the reaction.

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
