# Need help with this astronomy problem, just can't seem to get the right answer. I am multiplying to try and get the mass lost in one year and divide by the mass of lo (8.933*10*22). What am I doing wrong? Not too sure how to tackle part B either. Should I take 1% of the mass and divide by the amount lost in one year.
