A 84mL portion of 0.10M sulphuric acid was added to 80.0mL of a solution containing 5.10g of barium chloride (molar mass is 208.2 g/mole). Find the mass of barium sulphate (molar mass is 233.4 g/mole) that will precipitate.

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
