Density = mass/volume
D = 500 g /200 cm^3
D = 2.5 g/cm^3
hope this helps!
Well to find speed you have to do distance /time. So, in this case you do 112m /29s which it will be 3.862 which if you round it, it will be 3.86 m/s
If you are wanting the equation to be balanced it would be: P4 + 6Cl2 → 4PCl3

Below is the solution:
37.9*1000*1.03=39037 g=39.037 kg
39.037*2.21=86.28 lb
<span>86.28+59.5=145.78 lb <450 lb</span>
