Best ResponseYou've already chosen the best response.0It's asking, 'How many times would the mass of Mars 'fit into' the mass of the Sun'? Well, the mass of Mars would go into the mass of the Sun,\[\frac{m_{sun}}{m_{mars}}=\frac{1.998 \times 10^{27}}{6.421 \times 10^{20}}=3111664.85=3.112 \times 10^{6}\]in scientific notation to four significant places.
