To find the molar mass of a chemical do you add up all of the atomic masses of the elements in the chemical?
Yes- for example:
H2SO4
The molar mass for hydrogen is 1.008 g/mol, for sulfur is 32.07 g/mol, and that of oxygen is 16.00 g/mol. Note that these values may vary slightly depending on the Periodic Table that you use.
To find the molar mass:
(2 x 1.008) + 32.07 + (4 x 16.00) = 98.09 g/mol

How do you calculate the molar mass of a compound?
To calculate the molar mass of a compound, you add up the atomic masses of all the elements in the compound as indicated by its chemical formula. The atomic masses can be found on the periodic table.
How is the molar mass of a compound determined?
The molar mass of a compound can be determined by adding up the atomic masses of all the atoms in the compound as indicated by its chemical formula. The atomic masses can be found on the periodic table of elements. This total sum in grams per mole gives the molar mass of the compound.
What do the molar masses of any two elements contain the same number of what?
Atoms have atomic weight not molar mass. Any atom-gram has 6,022 141 29(27)×1023 (this is the number of Avogadro) atoms.
What is the molar mass of M on the periodic table?
The atomic mass of an element is listed on the periodic table, generally below the name of the element. The molar mass of a molecule will be generally be the sum of the atomic masses of the elements that make up the molecule.
How can one determine the molar mass of a solute?
To determine the molar mass of a solute, you can add up the atomic masses of all the atoms in the chemical formula of the solute. This can be found on the periodic table.

How is the molar mass of a compound determined?
The molar mass of a compound can be determined by adding up the atomic masses of all the atoms in the compound as indicated by its chemical formula. The atomic masses can be found on the periodic table of elements. This total sum in grams per mole gives the molar mass of the compound.
What two pieces of information are needed to determine the ratio of elements in a compound?
The chemical formula of the compound (e.g., H2O for water) and the molar masses of the elements present in the compound are needed to determine the ratio of elements. The molar masses are required to calculate the molar ratios of the elements in the compound.
How do you find molar mass?
you need to find the relative atomic mass. without that, you can't find that information unless given to you. basically, molar mass is a mole. a huge unit, but if you have that one "mole" of hydrogen atoms, you will have a equivalent of 1 gram The molar mass is the sum of the atomic weights of elements contained in the molecule, expressed in g/mole.
What do the molar masses of any two elements contain the same number of what?
Atoms have atomic weight not molar mass. Any atom-gram has 6,022 141 29(27)×1023 (this is the number of Avogadro) atoms.
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
What properties of elements did mendeleev list as he began to organize the elements?
Mendeleev listed the atomic weights and chemical properties of elements as he began to organize them. He noticed that elements with similar properties appeared at regular intervals when arranged by increasing atomic weight.
What is the molar mass of M on the periodic table?
The atomic mass of an element is listed on the periodic table, generally below the name of the element. The molar mass of a molecule will be generally be the sum of the atomic masses of the elements that make up the molecule.
How can one determine the molar mass of a solute?
To determine the molar mass of a solute, you can add up the atomic masses of all the atoms in the chemical formula of the solute. This can be found on the periodic table.
Is defined as the sum of the atomic masses in the molecule?
This is the molar mass.
What is the scientific definition of a molar mass?
The molar mass is the mass of a substance (in grams) per mole of that substance. It is calculated by summing the atomic masses of all the atoms in a chemical formula. Molar mass is expressed in g/mol.
What is the molar mass of all ther elements?
The molar mass of an element is the atomic mass of that element expressed in grams/mol. The molar mass of each element varies depending on its atomic number and isotopic composition. Common elements like hydrogen, carbon, oxygen, and nitrogen have molar masses of approximately 1 g/mol, 12 g/mol, 16 g/mol, and 14 g/mol, respectively.
