A10 liter flask at 298 k contains a gaseous mixture of o2 and co2 at 1 atmosphere. which statement is true for the partial pressures of o2 and co2 if 0.2 mole of o2 is present in the flask? (given the universal gas constant r = 0.082 l∙atm/k∙mol)

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
