Question

This is a chemistry question:
A material will float on the surface of a liquid if the material has a density less than that of the liquid. Given that the density of water is approximately 1.0 g/mL, will a block of material having a volume of 1.2 x 10^4 in^3 and weighing 350 lb float or sink when placed in a reservoir of water? [I just don't want the answer, I'd like to know how to solve this, please.]

Answer 1

you know the density o water, then find the density of the block. but remember to use the same system of measurements in both densities (I can see g/mL and in, lb in the same problem) use Metric System OR Standard System. 350 pounds divided by 1.20x10^4 cubic inches will give you density in standard system
