The element weirdium (We), found only on the planet Crosbia has only two isotopes; We-60 (60.00 amu) and We-90 (90.00 amu)! The average atomic mass of a naturally occurring sample
of weirdium is 70.00 amų. Calculate the percent abundance of We-60.

It starts to rust i think

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
