Ineed some on these problems:
1) a swimming pool measures 9.0 m long by 3.5 m wide by 1.75 m deep. what mass of water in metric tons (1 metric ton = 1000 kg) does the pool contain when filled? the density of the water is 0.991 g/cm3.

2) if a liquid has a density of 1.17 g/cm3, how many liters of the liquid have a mass of 3.75 kg?

3) when a sample of a metal alloy that has the mass of 9.65 g is placed into a graduated cylinder containing water, the volume reading in the cylinder increases from 16.0ml to 19.5ml. what is the density of the alloy sample in grams per cubic meter?
