When two elements form a series of compounds, the ratio of masses that combine with 1 gram of the first element can always be reduced to small whole number D. Each atom of oxygen is 16 times more massive than an atom of hydrogen E. At the same temperature and pressure, equal volume of different gasses contain an equal number of particles Oxygen, therefore, has a greater mass than carbon. 1 mole is equal to 1 moles In, or 114.818 grams. From the Periodic Table of Elements, one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams. Here comes the key part. Oxygen have atomic mass of 16 amu. The answer is 15.9994. (We need to do this, because knowing the number of moles of water will help us convert from grams to number of atoms!) A mole of carbon 12 atoms weighs 12g (which is where the definition comes from). calculate the gram atomic mass of one atom of oxygen. 14 g of Nitrogen = 1 mole of nitrogen. Define gram atom.

Use this page to learn how to convert between grams Oxygen and mole. We know, that oxygen weighs in at 1.33 times that of carbon, because of this we get a ratio of their masses: 16.0 amu (for one atom of O) = 1.33 12.0 amu (for one atom of C) 1. mass of one atom O = 2.6577076 × 19^-23 g O = 2.66 × 19^-23 g O rounded to three significant figures Answer: The mass of 1 atom of oxygen is approximately 2.66 × 19^-23 gram. Therefore 6.022*10²³ atoms weigh 16 grams hence ...in 1… The number of protons in the atom. One gram atom of carbon is the atomic weight (14 in the case of carbon) in grams, so it would be 14 grams of carbon. Mass of 1 oxygen atom = 16/6.022 × 10 23. 4. How many molecules does one gram of oxygen contain? Therefore 1 gram of elemental aluminum contains [(6.02 x 10^23) divided by 13] atoms. The mole (symbol: mol) is the unit of measurement for amount of substance in the International System of Units (SI). ... there is one atom of oxygen and two atoms of hydrogen. The number of atoms in one gram atom of any element is equal to Avoga-dro’s number, that is, 6.02252 x 10 23. 7 ; 1 mol of oxygen weighs 16 grams .
