Answer:
The atomic mass of methane (CH4)is 12 amu for the carbon plus 4 x 1 amu for the four hydrogens, for a total of 16 amu. Therefore, the molar mass of methane is 16g.
If you are looking for a one specific electron you will have 90% chance of finding it in an area within the atom electron clouds.
According to the wave mechanical or electron cloud model of the atom, postulates that the atomic orbital is a region in space where there is a very high probability of finding an electron.
The term "electron cloud" is just another term used for "atomic orbital".
Since electrons reside in orbitals, if you are looking for a one specific electron you will have 90% chance of finding it anywhere within the electron clouds. This would make mathematical sense as the probability of finding an electron within the electron cloud can never be 100%.
