Ahelium filled balloon has a volume of 208 l and it contains 9.95 moles of gas. if the pressure of the balloon is 1.26 atm determine the temperature

Compare the valence electron configuration of the nobles gas elements seen here. what statement is correct?

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

Is this correct if not can u correct me
