The mass number of an atom is obtain by totaling the number of what?
The mass number of an atom is obtained by totaling the number of protons and neutrons.
How do you obtain the mass number of an atom?
in order to obtain the mass number of an atom you must get the number of neutrons + the number of protons which = the mass number !!!hope this helped!!! :)
How is the number of moles of an element determined from known mass?
The molar mass is the measurement of mass per one mole of a substance. If the mass of a matter is known, divide it from the molar mass to obtain the number of moles.
Would you use atomic number or mass number or both to obtain the number of particles in an atom?
atomic number is the total number of protons OR electrons in an atom. mass number is the total sum of number of protons and neutrons. atomic number subtracted from mass number gives the number of neutrons in an atom. Mass number - atomic number = number of neutrons.
How can you dertermine the number of neutrons in a isotope?
Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.
The sum of the protons and the neutrons indicates the .?
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
What is indicated by the sum of protons and the neutrons?
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
The number of moles of oxygen in the reaction vessel is?
To calculate the number of moles of oxygen in the reaction vessel, you need to know the amount of oxygen in grams and its molar mass. Then divide the mass of oxygen by its molar mass to obtain the number of moles. The formula to calculate the number of moles is: moles = mass / molar mass.
When we subtract the atomic number from the mass number what do we get?
When we subtract the atomic number from the mass number, we obtain the number of neutrons in an atom. The atomic number represents the number of protons, while the mass number is the sum of protons and neutrons in the nucleus. Therefore, the calculation gives us the total number of neutrons present in that particular isotope of an element.

How is the number of moles of an element determined from the known mass?
To determine the number of moles of an element from its known mass, you can use the formula: moles = mass / molar mass. First, find the molar mass of the element from the periodic table. Then, divide the given mass of the element by its molar mass to find the number of moles.
When you subtract the atomic number from the atomic mass of any element you get what?
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
