1. The problem statement, all variables and given/known data My problem is with the number of significant figures I have to carry forward in intermediate calculations. I know that if the given data has a minimum of n sf, then the final ans should be to n+1 sf. But then should the intermediate answers be to n+2 sf?? 2. Relevant equations 3. The attempt at a solution I have no idea how to solve this problem. Please help!!
