I'm trying to do a lab for my physics class. It wants me to calculate the weight of the water displaced when I put a 500-g mass in a cup of water. I know the volume wich is 59.0 ml. And I also know that the Buoyant force i s 0.56 N. I thought that the Buoyant force equals the volume of the water displaced but my friend told me that I have to convert the volume (59.0 ml) to Newtons. I was wondering which one of us was right and if my friend was right i was wondering how to convert ml to Newtons.
