What information is given by a molecular formula?
the empirical formula and the molar mass
What information does the percent composition in an atom in a molecule give?
The relative amount of mass an atom contributes to a molecule
How do you determine the gram mass of an element in a molecule if you know the gram mass for the molecule and its molecular weight?
To determine the gram mass of an element in a molecule, you first need to know the molecular formula of the molecule, which indicates the number of each type of atom present. Calculate the molar mass of the entire molecule based on the atomic weights of its constituent elements. Then, find the molar mass contribution of the specific element by multiplying its atomic weight by the number of atoms of that element in the formula. Finally, use the ratio of the element's molar mass to the total molar mass of the molecule and multiply by the total gram mass of the molecule to find the gram mass of the element.
The formula mass of a molecule or an ion is?
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
What is the gram molecular mass of sulfur molecule?
The gram molecular mass of a sulfur molecule (S8) is 256 grams per mole. This is calculated by adding up the atomic mass of each sulfur atom in the molecule. Each sulfur atom has an atomic mass of 32 grams per mole, and there are 8 sulfur atoms in a sulfur molecule.

What are the relative formula masses of hydrogen molecules?
The relative formula mass of a hydrogen molecule (H2) is calculated by adding the atomic masses of the two hydrogen atoms. Each hydrogen atom has an atomic mass of approximately 1, so the relative formula mass of a hydrogen molecule is 2.

Does a molecule have mass?
Yes. For example water molecules (2 hydrogen connected to 1 oxygen atom) have a bent shape.
What does percent composition tell you about 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
Why the mass of hydrogen molecule is greater then the mass of hydrogen atom?
The mass of a hydrogen molecule is greater than that of a single hydrogen atom because a hydrogen molecule consists of two hydrogen atoms bonded together. When two hydrogen atoms bond to form a molecule, they share electrons, resulting in a decrease in the individual mass of each atom. However, the total mass of the molecule is slightly higher due to the binding energy that holds the atoms together.

The gram molecular mass of a sulfur molecule (S8) is 256 grams per mole. This is calculated by adding up the atomic mass of each sulfur atom in the molecule. Each sulfur atom has an atomic mass of 32 grams per mole, and there are 8 sulfur atoms in a sulfur molecule.
What is the formula mass of hydrogen?
The relative formula mass of a molecule of hydrgoen is two (2 x 1).
An electron has?
a molecule is made up of more than one atom, but they do not have to be different types of atoms. such as with H2 is a diatomic atom as apposed to water (H2O) which is a molecule made of 2 different types of atoms. some molecules can have many different types of atoms combined into that one molecule
