In Qinghai yacht, there is a tourist want to roughly measure the density of the lake, he will be in his hands with 596 milliliters of pure water light transparent beverage bottle into the lake.

1, the density of pure water is about 1g/cm^3, negligible transparent plastic bottle.

Because the bottle floats on the surface of the water, F float = pgV row = G = mg = 596*1*10/1000 = 5.96N

2. V row = 596-100 = m/p water - 100 = 596/1-100 = 496ml

F float = pgV row = G = mg

So p = m/V row = 596*1/496 = 1.2g/cm^3

i.e. the density of the lake water is 1.2g/cm^3
