What is the atomic mass for capsaicin (C18H27NO3)?

First, the substance a compound and therefore its smallest unit is a molecule NOT an atom. It therefore cannot have a ATOMIC mass it must have a MOLECULAR mass which will be the sum of all masses of all the atoms comprising the molecule. The molar mass of C18H27NO3 is : 305.41 g/mol.


What is the sum if the masses of the atoms present in the formula of an ionic compound?

The sum of the masses of the atoms in an ionic compound is equal to the formula mass of the compound. It is calculated by adding the atomic masses of all the atoms present in the formula unit.


How would we determine the molecular weight for a molecule water h2o?

To determine the molecular weight of a molecule like water (H2O), you would add up the atomic weights of all the atoms in the molecule. For water, you would add the atomic weight of two hydrogen atoms and one oxygen atom, which gives you a molecular weight of approximately 18.015 atomic mass units (amu).


What are the sum of atomic masses of all atoms formula for a compound called?

It is called the molar mass of that compound. In other words, the total mass of all of the elements in a compound is equal to one mole of that compound.


What is the mass in gram of one molecule of caffeine (C8H10N402)?

To calculate the mass of one molecule of caffeine (C8H10N402), you need to add up the atomic masses of all the atoms it contains. The molar mass of caffeine is approximately 194.19 grams per mole. One molecule of caffeine will have a mass of 194.19 grams.

Can Atomic mass be used to determine molecular mass?

Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.


What is the sum of the atomic masses in a molecule?

The sum of the atomic masses in a molecule is called the molecular weight or molecular mass. It is calculated by adding the atomic masses of all the atoms in the molecule. This value is usually expressed in atomic mass units (amu) or grams per mole (g/mol).


How do you find the atomic mass of C7H8?

You mean molecular mass or moler mass, not atomic mass! Add up the atomic masses of all the atoms in the molecule.


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.


How do you calculate Mr?

To calculate the relative molecular mass (Mr) of a molecule, add up the atomic masses of all the atoms in the molecule as shown in its molecular formula. For example, the Mr of H2O (water) is calculated by adding the atomic masses of 2 hydrogen atoms and 1 oxygen atom.


What is the mass of one molecule of a nonionic substance in atomic mass units?

The mass of one molecule of a nonionic substance in atomic mass units can be determined by adding up the atomic masses of all the atoms it contains. This can be found by looking up the atomic masses of each element on the periodic table and summing them together.


What is the atomic mass of starch?

The atomic mass of a starch molecule is calculated by adding up the atomic masses of all the atoms it contains. Since starch is composed of carbon, hydrogen, and oxygen atoms, the atomic mass can vary depending on the specific ratio of these atoms in the molecule. The average molecular weight of starch is around 162 grams per mole.


What is the Grand formula mass?

The grand formula mass is the sum of the masses of all the atoms in a single molecule of a compound, including all elements present in that compound. It is calculated by adding up the atomic masses of each element involved in the molecule.
