Answer
Density =$ 1.6 * 10^6$ $grams/m^3$
Work Step by Step
$density = mass/volume$
$mass = 1.02*10^{26}$ kg
$mass = 1.02*10^{26}*10^3$ g
$mass = 1.02*10^{29}$ g
$radius = 2.48* 10^4$ km
$radius = 2.48* 10^4*10^3$ m
$radius = 2.48* 10^7$ m
$V = 4/3*\pi*r^3*1000$
$V = 4/3*\pi*(2.48*10^7)^3$
$V = 4.18879 *15.252992*10^{21}$
$V = 63.8915803597 * 10^{21}$
$V = 6.389 * 10^{22}$
$density = mass/volume$
$density = 1.02* 10^{29}/6.389 *10^{22}$
$D = 1.02/63.89 * 10^{29}/10^{22}$
$D = .0159645 * 10^{29-22}$
$D = .0159645 * 10^{7}$
$D = 1.59645 * 10^{6}$
$D = 1.597 * 10^{6}$
