P. 4326. A vessel, filled with water, is placed to a very accurate scale, and the reading on the scale is 308.48 g. A block which hangs on a spring balance is totally immersed into the water. Now the reading on the scale is 336.43 g. What is the reading on the spring balance if it was 1.75 N before the block was immersed into the water? What is the density of the block?
