User: what is molar mass

Weegy: A 1 molar solution is a solution in which 1 mole of a compound is dissolved in a total volume of 1 litre.

For example:
The molecular weight of sodium chloride (NaCl) is 58.44, so one gram molecular weight (= 1 mole) is 58.44g. If you dissolve 58.44g of NaCl in a final volume of 1 litre, you have made a 1M NaCl solution.

User: what is relative atomic masses?

Weegy: The atomic mass is sometimes incorrectly used as a synonym of relative atomic mass, average atomic mass and atomic weight. [ These differ subtly from the atomic mass. The atomic mass is defined as the mass of an atom, which can only be one isotope at a time and is not an abundance-weighted average as in the case of atomic weight. An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of an atom of 12C. and The atomic mass is the mass of a specific isotope, most often expressed in unified atomic mass units. The atomic mass is the total mass of protons, neutrons and electrons in a single atom. I hope it can help you.. Good Luck :) http://answers.yahoo.com/question/?qid=20120811104436AATwXTd ]

User: what is the avogadro's constant?

Weegy: None, as far as I know. Both are just a number, 6.02E23. [ The value of this constant is popular amongst chemistry teachers, but actual chemists never use it. http://answers.yahoo.com/question/?qid=20091016073910AAKGjB8 ]
