Final Answer

Thank you for the opportunity to help you with your question!

:V(escape)= squareroot[(2GM)/r] 

 23,300= squareroot[2* 6.67 × 10^-11 * M /2.48 × 10^7 ]

542890000 = 13.34*× 10^-11 * M /2.48 × 10^7

M=1008877499025867 = 10* 10 ^14 kg

Please let me know if you need any clarification. I'm always happy to answer your questions.
