The element rhenium has two naturally occurring isotopes, 185 re and 187 re, with an average atomic mass of 186.207 amu. rhenium is 62.60% 187 re, and the atomic mass of 187 re is 186.956 amu. calculate the mass of 185 re. how do you do this?

Water is important for the of cells. a: size, shape, and temperature b: temperature, color, and odor c: color, odor, and size d: shape, temperature, and color

The molecular weight of carbon dioxide, co2, is 44.00 amu, and the molecular weight of nitrous dioxide, no2, is 46.01 amu, so no2 diffuses co2

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
