The student investigated the effect of changing the temperature of the sodium thiosulfate
solution on the rate of reaction.
She plotted her results on a graph, as shown in Figure 2.

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
