The volume of a ball is given in terms of its radius by V=4π3R3. Use this to find the average density of Saturn, i.e. the mass per unit volume. Use Earth’s mass in kg from the Table of Constants to express your answer in kgm3. Note for comparison that water has a density of about 1,000 kgm3. Please round your answer to two significant digits.
