Explain why the atoms need to be ionized before element x atoms can be deflected in a mass spectrometer?
The atom needs to have a charge to be deflected (as an electromangets are being used - magnets work with charge) so by ionising the atom, it loses an electron and gains a positive charge.
What is the atomic mass of milk?
Milk is a solution of many different atoms. Atomic mass only refers to the mass of a single type of atom. Milk may have a "molecular mass" but you need to determine all of the different atoms in milk and then add their masses together.
Calculate Mass of cell?
To calculate the mass of the cell you will need to know the mass and atomic number of the element. Multiply the number of atoms by the amount of grams per mole to get the mass.
What is the need to use telescope in spectrometer?
The collimator present in a spectrometer convert the rays from the source to parallel rays .Telescope is used to watch the parallel rays which means for the telescope the object is located at infinity.so that we use telescope.
How many atoms are in 9 mol of atoms?
For this problem you don't need the atomic mass of the element. If you want to convert moles to atoms, you need to take the number of moles and multiply it by Avogadro's constant, 6.02 × 1023. Divide by one mole for units to cancel.9.00 moles C × (6.02 × 1023 atoms) = 5.42 × 1024 atoms C

How many atoms are in Pepsi?
You would first need to know the mass of the soda cap. This is how you would do it.... the mass multiplied by 1 mol/the molar mass multiplied by 6.02x1023 . Then you would be left with the about of atoms.

What information do you need to know to determine the chemical formula of an unknown compound?
We need to know the elements contained in this molecule and the percentages.
How do you convert from atoms to mass and from mass to atoms?
moles to atoms you multiply the number of moles by avogadros number ex: 1.32 mol x (6.022 x 10^23 atoms)/mol mass to atoms you multiply the mass (in grams) times the molar mass of the element or compound (ex: N 14.01 mols/gram) then times avogadros number once you have the moles. ex: 45.6 g N x (14.01 mol/gram) x (6.022 x 10 ^23 atoms/mol) if it's a compound instead of an element, find the molar mass of the compound (the molar masses of all the elements in it added up) and multiply by it. ------------------------- Actually you are wrong, from mass to atoms you need to take the initial mass divide by the gram of the element that you are doing and multiply by the Avogadros number
What tells an atoms mass?
This tells us that an atom of krypton has 36 protons in its nucleus. All you really need to find is something called the mass number.
What is the mass of 1.505 x 10²³ carbon atoms?
To convert atoms to grams, you need to take the number of atoms, divide it by Avogadro's Constant, then multiply it by the atomic mass.Atoms ÷ (6.02 × 1023) × Atomic mass = Mass in grams1.505 × 1023 ÷ (6.02 × 1023) × 12.0 = 3.00 grams Carbon
How many atoms are in a 1cm of copper wire and who calculate this?
We need to know the diameter of the wire to calculate the volume and the mass. Number of atoms is: 2,58.1023.r2, where r is the radius of the wire.

How many atoms are in 70.620 g of rhenium?
To determine the number of atoms in a given mass of an element, you need to know the molar mass of that element. The molar mass of rhenium (Re) is 186.207 g/mol. To find the number of atoms in 70.620 g of rhenium, divide the given mass by the molar mass, and then multiply by Avogadro's number (6.022 x 10^23). This gives approximately 1.590 x 10^23 atoms of rhenium.
