The mass of the planet is 6.67×10^25 kg

let the mass of the planet be M and r be the radius of the planet and g be the gravitational acceleretion.

then:the gravitational acceleration is given by:

g = G×M/(r^2)

M = g×r^2/G

= [(18)×(1.2×10^7)^2]/(6.67408×10^-11)

= 6.67×10^25 kg

therefore, the mass of the planet is 6.67×10^25 kg
