Two oxides of a metal contain 27.6% and 30% of oxygen respectively. If the formula of the first oxide is MO, find that of the second? Now my problem is how to find the atoms of O from the masses of 27.6% and 30.0 %? How to get atoms of something having % of mass? I am conf...
or the average mass, in a group of atoms. However, electrons have so much less mass than protons and neutrons that they don't factor into the calculation. So, the atomic mass is the sum of the masses of protons and neutrons. There are three ways to find atomic mass, depending on...
3\. Below the symbol is the atomic mass. While this number is a weighted average of the masses of all isotopes of the element, if you round the number to the nearest whole number you will find the mass number of the most common isotope. For carbon the mass number (M) is 12. This ...

The orbiter could spot objects as small as a dinner plate, while also carrying sounders to find subsurface water. Perhaps most importantly, it's still a crucial communications tool for relaying information back to mission control. But let's wander over to the rovers' predecessors. Viking 1 and...

Atomic mass and atomic mass unit Each element in theperiodic tableconsists of atoms, and each atom has a unique atomic mass and unique atomic number. The atomic number refers to the number of protons in the atom's nucleus, while atomic mass reflects the sum of the number of protons and ...
