1. The problem statement, all variables and given/known data A hollow sphere has average density of 3 g/cm^3 and a mass of 120g. What will the sphere weight under water? correct answer: 0.8 2. Relevant equations d=m/v w=mg 3. The attempt at a solution I converted 120g into kg and then used w=mg to find weight on land. however, this does get 0.8N underwater. Please help thanks!
