What is the atomic mass of nitrogen?

The atomic mass of Nitrogen is 14.0067the atomic mass of nitrogen is 14.007, so if you round off you will get 14


Atomic Mass and Atomic Number of neon?

The Atomic number of Neon is 10 and the Atomic weight is about 20.18g rounded off to 2 decimal places. If you don't have a periodic table you should get one most periodic tables have the atomic weight of all elements you need to know to around 2 decimals. I printed mine off Google images =)


Gram atomic mass of 1 mole of aluminum?

This question is a little confused. The gram-atomic mass for aluminum is approximately 27 (look at a periodic table if you want more significant figures; I don't recall them off the top of my head). It doesn't matter if you have a mole or a planet-sized mass of the stuff, the gram-atomic mass is always going to be the same.

Can magnesium's mass be 24 after rounding it off?

No, magnesium's atomic mass is approximately 24.31 amu (atomic mass units). Rounding this value to the nearest whole number would still give 24.

the oxygen burns away so the mass off the object will increase


How do you calculate how many neutrons there are in an atom?

The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number. Take for example, Uranium: the mass number on the periodic table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons. 238-92=146


How can the number of neutrons in an atom be determined?

1. Locate the element on the periodic table.2. Find the element’s atomic number (which is the same as the number of protons)3. Find the element’s atomic weight.4. Round off the atomic weight to the nearest whole number to find the atomic mass.5. Subtract the atomic number from the atomic mass (The numbers after the decimal point represent the usually very small mass of the electrons in the atom.)


Would a calculation of the atomic mass of a metal be too high or too low if your hot metal sample cooled off while being transferred to the calorimeter?

If the metal sample cooled off during transfer to the calorimeter, the atomic mass calculation would likely be too low. The cooling of the sample might cause a loss of energy, leading to a lower measured heat capacity and an underestimation of the atomic mass.

What do you get if you add one neutron to a hydrogen nucleus?

If you add the number of protons and neutrons in an atomic nucleus, you get the number of nucleons. This is usually a good approximation to the atomic mass in amu, since both protons and neutrons have a mass that's pretty close to one amu. The number will be slightly off, because electrons contribute as well, protons and neutrons don't have exactly the same mass, and there's something called the atomic mass defect that has to do with the binding energy of the nucleus, but it should be fairly close.


What is 776 rounded off?
