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.

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.


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 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.


How do you find no of atoms if molar mass and density is given?

This is actually a chemistry question, but I found it in the math section... well anyways you use an equation with avogadro's number. P(density)=(((#atoms)(molar mass))/((avogadro's number)(volume))). You're solving for #atoms so rearrange the equation. You have density, molar mass, and avogadro's number. As for volume, assuming you know what element this is (which you should know from the molar mass even if it's not given), you should be able to compute volume from the unit cell measurements. If you do not know unit cells... I'm not sure.

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 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.

What mass of copper contains the same number of atoms as 68.7 g of iron?

To find the mass of copper containing the same number of atoms as 68.7 g of iron, we need to first calculate the number of atoms in 68.7 g of iron using its molar mass. Then, we convert this number of atoms to copper atoms using the ratio of their molar masses. Finally, we determine the mass of copper corresponding to this number of atoms.
