A substance has a mass of 2.5 kg and a volume of 2500 mL, what is the density of the substance in g/mL? All answers must have the correct unit! (g/mL) d= mass/volume, d= masa/volumen

When a scientific theory has been tested and proved by the scientific community, it becomes a law

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
