The mass of a nitrogen-14 atom is 14.00307 amu. O is 16 grams/mole, and 16 amu/molecule. The same concept can be extended to ionic compounds and molecules. So, answer (b) is correct. Because the atomic mass of hydrogen is 1.0079 amu, what can be concluded about the two isotopes? The isotopes hydrogen-1 and hydrogen-2 make up nearly all of the hydrogen found in nature. An atomic mass unit (symbolized AMU or amu) is defined as precisely 1/12 the mass of an atom of carbon-12. Relevance. Favorite Answer. Which of the following represents 1 amu? The molar mass of nitrogen (N) is approximately 14.01 grams per mole of nitrogen atoms. Molar mass is the quantity of an element in grams for every one mole of atoms of that element. The mass of an atom of hydrogen-1 is 1.0078 amu, and the mass of an atom of hydrogen-2 is 2.0141 amu. The number of atoms of nitrogen in one molecule of it is m. O2 is 32 g/mole because there are 2 of them. Numerically, it's the same as the element's atomic mass in units of amu (atomic mass units). Therefore, gram atomic mass of nitrogen atom = 14 g ( since, atomic mass of nitrogen = 14u) Mass of one mole of an atom equal to gram atomic mass of atom . Therefore, mass of one mole of nitrogen = 14g Answer Save. (6.022x10^23 molecules/1 mol)(1.79 mols TNT)(3 atoms N/1 molecule) = x atoms N Calculators are a wonderful thing. The nuclear binding energy of one nitrogen-14 atom is … Minimum molar mass of the compound is n × 1 0 2 g/mol. N = nitrogen nitrogen has an atomic mass of 14.00674 amu Hope this helps :) ... each with a mass of about 16 AMU and 1 carbon atom with a mass of about 12 AMU for a total mass of 44. Question 5. 2 Answers. It's only the units that change. In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams. Valium -- find the molar mass. The mass of one atom is usually expressed in atomic mass units (amu), which is referred to as the atomic mass. (a) Mass of a C – 12 atom (b) Mass of a hydrogen atom (c) $$\frac { 1 }{ 2 }$$th of the mass of a C – 12 atom (d) Mass of O – 16 atom Answer: (c) 1 / 12th of the mass of a C – 12 atom Hint: By definition 1 amu is defined as precisely 1 / 12th the mass of an atom of carbon – 12. Anonymous. Which of the following represents 1 amu? This number, 12.01, is the mass in grams of one mole of carbon. Gram atomic mass of an element is the amount of that element in grams whose quantity is equal to atomic mass of that element. It is equal to 1 mole of Nitrogen atoms. I would like if you could show the work so I can see where I'm going wrong. Uumm, the amu weight (molar mass) ARE THE SAME. One mole of carbon is 6.022 x 10 23 atoms of carbon (Avogadro's number).This relation is then used to 'convert' a carbon atom to grams by the ratio: An amu is defined as exactly $$1/12$$ of the mass of a carbon-12 atom and is equal to 1.6605 $$\times$$ 10 −24 g. Protons are relatively heavy particles with a charge of 1+ and a mass of 1.0073 amu. Caffeine has a molecular weight of 194. What is the mass of a single nitrogen atom in grams? One formula unit of sodium chloride (NaCl) would weigh 58.44 amu (22.98977 amu for Na + 35.453 amu for Cl), so a mole of sodium chloride would weigh 58.44 grams. 9 years ago. A compound of Mg contains 6% Mg by mass. A mole, or mol for short, is a quantity of any given thing that is equal to 6.02214 * 10^23 particles. Round to the 5es001-1.jpg decimal place. The question also states that the molar mass of nitrogen (N2) is 28.0 g/mole. The mass defect of nitrogen-14 is __ amu. It contains about 30% by mass of nitrogen. (b) 14 amu Hint: Atomic mass of Nitrogen is 14.00674 grams. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. To calculate the mass of a single atom, first look up the atomic mass of carbon from the periodic table. The mass of a proton is 1.00728 amu, and the mass of a neutron is 1.00866 amu.
