The molar mass of an element is equal to?
The element's average atomic mass.
What is a rule for determining the mass?
Just adapt the formula for density to find the mass of an object. After adapting it, it should be like this: Volume*Density=Mass
What is the rule for determining the mass number of an atom or ion?
The mass number is the sum of number of protons and neutrons in the atomic nucleus.
What letters are used to designate atomic number and mass number in isotopic notation of atoms?
Each chemical symbol is for a chemical element; each chemical element has a specific atomic number and an atomic weight (not mass, after the rule of IUPAC).
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
The molar mass of an element is equal to?
The element's average atomic mass.
What is the average mass of an atom?
That depends on the atom in question. What element is it of? The periodic table should be helpful in determining atomic mass.
What is a rule for determining the mass?
Just adapt the formula for density to find the mass of an object. After adapting it, it should be like this: Volume*Density=Mass

What is the rule for determining the mass number of an atom or ion?
The mass number is the sum of number of protons and neutrons in the atomic nucleus.
When determining the mass of your friend what do you use?
A mass balance.
What determines an element's mass?
the mass of protons + the mass of neutrons = mass of the element
What letters are used to designate atomic number and mass number in isotopic notation of atoms?
Each chemical symbol is for a chemical element; each chemical element has a specific atomic number and an atomic weight (not mass, after the rule of IUPAC).
The birthday rule applies to determining what?
Fractions
What do you call the mass of an element?
The mass of an element is known as it's ATOMIC Mass.
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
