For 2: Neutron Number and Mass Number of Nitrogen. Molar mass … After researching in many books to find the mass of the earth's atmosphere, I found out that the answer is approximately 5 × 10 18 kg. Mass of nitrogen in = 14 g/mol. Everything has mass and volume, and therefore density. Hence, Mass of nitrogen in will be 138.47 grams. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. The atomic mass of nitrogen is 14.00674 atomic mass units. Calculate the number of atoms in 39.4 g gold. Without chemical processes involving several of the atmospheric gases, life could not exist. Nitrogen is a gas that has the atomic number 7 and the chemical symbol N. There are 7 neutrons, 7 protons and 7 electrons in a nitrogen atom. 1 answer. As, in 101.1 g/mol of contains 14 g/mol of nitrogen.. Nitrogen also has stable isotopes, such as N-14 and N-15. Explanation: Conversion factor: 1 kg = 1000 g For 1: Molar mass of = 101.1 g/mol. 1 mole of nitrogen atoms is equivalent to the gram atomic mass of nitrogen. Answer: For 1: Mass of nitrogen will be 138.47 grams. Next, you can probably find the mass of an electron which you can also convert to kg. Finding molar mass starts with units of grams per mole (g/mol). Gram atomic mass of nitrogen = 14 g Therefore, 1 mole of nitrogen atoms contains 14 g. Related questions 0 votes. The atmosphere is mostly made up of oxygen and nitrogen in their diatomic forms. What is the mass of a single nitrogen atom in grams? About Nitrogen gas; 1 cubic meter of Nitrogen gas weighs 1.251 kilograms [kg] 1 cubic inch of Nitrogen gas weighs 0.000723124 ounce [oz] Nitrogen gas weighs 0.001251 gram per cubic centimeter or 1.251 kilogram per cubic meter, i.e. For 2: Mass of nitrogen will be 350 grams. (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. A nitrogen atom has seven electrons. In the case of Nitrogen , density is 0.0012506 g/cm³. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). So, 1000 grams of will contain = of nitrogen.. I would like if you could show the work so I … 2 moles N X 14.01 grams N-----1 Mole N. Then moles of N cancel and you are left with 28.02 (2X 14.01) But if the question in asking for N2 which is the most common form of Nitrogen because it is diatomic then you would use the same formula except you would multiply 2 X 28.02. So it is expected that the smallest piece of matter, like an atom of Nitrogen has it too. Weights of atoms and isotopes are from NIST article. The question also states that the molar mass of nitrogen (N2) is 28.0 g/mole. What you do is find the molar mass of N from periodic table = 14.01g. In the ground state, they are arranged in the electron configuration 1s 2 2s 2 2p 1 x 2p 1 y 2p 1 z.It therefore has five valence electrons in the 2s and 2p orbitals, three of which (the p-electrons) are unpaired. Note: Learn more about the density here. But what is the density of an atom of N? Mass numbers of typical isotopes of Nitrogen are 14; 15. Then, subtract the mass of the electron for the mass of the atom to get the mass of a single sodium ion: So, 22.98977 g/mol / 6.022045X10^23 = 3.817602 X 10^-23 g/atom X 1 kg/1000 g = 3.817602 X 10^-26 kg. Then, convert that to kg.
