Question

The final formula in my textbook is relative density= weight of object in air / weight of object in air - weight of object in water * density of water . So, how did the mass change into weight???

Answer 1

Answer:

To calculate the weight, W, in Newtons, you multiply the mass, m, in kilograms times g: W = mg. To get mass from weight, you divide the weight by g: m = W/g
