539.28kJ x (1mol/ 6kJ) x (28g / mol N2) x (1mL/11g) x (1L/1000mL) = ? Please only answer if you know it! I worked very hard for these points and this question is super important to a project I have due tomorrow. I made it myself I just forgot how to do the conversions oops...

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
