You mean molecular mass or moler mass, not Atomic Mass!
Add up the atomic masses of all the atoms in the molecule.
What else can I help you with?
What is the percent by mass of h in c7 h8 the molecular weight of carbon is 12.0107 gmol and of hydrogen 1.00794 gmol answer in units of your answer must be within 1?
mass of h = 8 atoms of h/molecule * 1.00794 g/mol = 8.06352g/mol of h in c7h8 mass of c7h8 = 8 atoms of H/molecule * 1.00794 g/mol + 7 atoms/molecule of C * 12.0107 g/mol = 92.13842 g/mol h / c7h8 = 8.06352 / 92.13842 = 0.08752 0.08752 = 8.752% = 9%
How do you find the atomic mass by adding what?
Atomic mass = Mass of protons + Mass of neutrons
How does the atomic mass help you find the neutrons?
Atomic mass = mass of protons + mass of neutrons.
What is the relationship btw atomic mass and atomic mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the difference between the atomic number mass number and atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the difference between the atomic number and average atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atomic mass of an element the number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you calculate the number of neutrons an element has in its nucleus?
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
Why is the atomic mass number not a whole number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why do you subtract the atomic number from the mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you find atomic mass?
23
How do you find electrons?
you can find electrons by subtract the atomic number and atomic mass.
