What is an atoms mass number?
neutrons + protons = mass number
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Avogadro's number of aluminum atoms has a mass equal to?
Thast is one mole. 26.98 grams/per mole is the mass.
How do you convert from grams to atoms and from mass to atoms?
To convert from grams to atoms, you need to use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the given amount of substance into moles and then multiply by Avogadro's number to get the number of atoms. To convert from mass (in grams) to the number of atoms, first find the molar mass of the substance, then divide the given mass by the molar mass to get moles, and finally multiply by Avogadro's number to obtain the number of atoms.
How do you find atoms if given molar mass?
To find the number of atoms in a sample when given the molar mass, first determine the number of moles by dividing the mass of the sample by the molar mass. Then, use Avogadro's number (approximately (6.022 \times 10^{23}) entities per mole) to convert moles to atoms by multiplying the number of moles by Avogadro's number. This will give you the total number of atoms in the sample.
What is mass proportional to the number that makes up an object?
atoms
What is an atoms mass number?
neutrons + protons = mass number
What mass of He contains the same number of atoms as 5.0 g Kr?
To find the mass of He containing the same number of atoms as 5.0 g Kr, we need to use the fact that atoms are indivisible entities. First, determine the number of atoms in 5.0 g Kr using the molar mass of Kr. Then, calculate the mass of He containing the same number of atoms by dividing the atomic mass of He by Avogadro's number and scaling it up to match the number of Kr atoms.
What thing makes up matter?
Mass and atoms
What is the mass in g of 9.44x10 23 atoms of lithium?
To calculate the mass of 9.44x10^23 atoms of lithium, you can use the molar mass of lithium, which is approximately 6.94 g/mol. Divide the number of atoms by Avogadro's number to get the number of moles, then multiply by the molar mass to get the mass in grams.
How many atoms of gold are in the bar?
The number of atoms in a bar of gold depends on the mass of the bar. To calculate the number of atoms, you would need to know the mass of the bar and the atomic mass of gold. You can use Avogadro's number to convert from grams to atoms.
How can Atoms vary?
Atoms and elements can vary in many ways. Atoms mainly vary by having different numbers of protons, electrons, and neutrons. The count of protons makes up an elements mass number.

What is the atoms mass number?
The Atomic Mass number tells how many protons and neutrons are in a nucleus.
What makes up the atoms mass number?
The mass number is the average total of the number of protons and neutrons in the atomic nuclei of all the isotopes of that element on earth. Thus, the average number of neutrons in that element can be found by subtracting the atomic number from the mass number.
