Jupiter has 67 confirmed moons. Four of the sixty-seven dominate the others (in terms of mass) and data of these four are given in the table. Based on the information given, calculate the mass of Jupiter. Each moon's information should be used for a separate calculation of Jupiter's mass. Does each moon give the same mass for Jupiter?
