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.
How would we determine the molecular weight for a molecule water h2o?
You add together the atomic weights of all the atoms (as given by its chemical formula) in the molecule
How many atoms contains a molecule of sucrose c12h22o11?
The atomic masses are available on all periodic tables. H = 1.0079 C= 12.001 O= 15.999 total mass = (12.001 x 12) + (1.0079 x 11) + (15.999 x 11) = 144.012 + 11.0869 + 175.989 = 331.0879 amu
Given the density of Br2 What is the molecular weight?
159.8 grams The masses (atomic mass) on the periodic table are the mass of 1 mole of the element. So all you have to do is find the atomic mass of bromine (79.9 grams) and multiply it by two since there are two atoms in the molecule.
What are the three subatomic particles of a molecule?
A molecule contains atoms e.g. water (H2O) The atoms, ( hydrogen and oxygen, and all other atoms) contain protons, neutrons in the nucleus of the atoms and electrons in energy shells around the nucleus. Protons, neutrons and electrons are sub-atomic particles.
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.
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.
The formula mass of a molecule or an ion is?
The formula mass of any molecule, formula unit, or ion is the sum of the average atomic masses of all atoms represented in its formula.
What is a molecular mass?
it is the sum of the atomic masses of all the elements present in a molecule.
What is the sum of atomic masses of all the atoms in a formula for a compound?
formula mass
The average of the masses of all the atoms in a sample of an element is called the?
This is the atomic weight.

Is the molecular weight the same as its atomic weight?
The molecular weight is the sum of the atomic weights of all the atoms contained in the molecule.
How do you calculate the mass of a plasmid that is 3000 base pairs?
The mass equals 3,000 * the average mass of a base * 2 [base pair]. To get the mass of a base we would have to total the atomic masses of all of the atoms in the base molecule.
Can the atomic mass of a molecule be found if the chemical formula is known?
Well first of all a molecule doesn't have an atomic mass it has a molecular mass. It's molecular mass is found by adding up the atomic masses of all the elements that make up the molecule. These atomic masses are found on a periodic table. For example water has a formula of H20. This means it is made of 2 hydrogen atoms and 1 oxygen atom. Hydrogen has an atomic mass of 1 g/mol while oxygen has an atomic mass of 16 g/mol. So the molecular mass of water is 2 x 1g/mol + 1 x 16 g/mol = 18 g/mol
