• The SI base unit for amount of substance is the mole. 1 grams neon is equal to 0.049554750566163 mole. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between grams neon and mole.
• 1 mole of phosphorus and 4 moles of oxygen. From the periodic table we see that 1 mole of potassium atoms weighs 39.10 g, 1 mole of hydrogen atoms weighs 1.008 g, 1 mole of phosphorus atoms weighs 30.97 g and 1 mole of oxygen atoms weighs 16.00 g. Thus, one mole of K2HPO4 will weigh: 2 K 2molK 39.10g x molK =78.20g 1 H 1molH 1.008g x molH =1.008g
• C) There are one thousand times as many neon atoms as bromine atoms. D) There are four times as many neon atoms as bromine atoms. E) There are four times as many bromine atoms as neon atoms. Ans: D 23. One mole of iron A) is heavier than one mole of lead (Pb). D) weighs the same as one mole of lead. B) is 77.0 g of iron. E) None of the above.
Neon comprises 1 part in 55,000 in the Earth's atmosphere, or 18.2 ppm by volume (this is about the same as the molecule or mole fraction), or 1 part in 79,000 of air by mass. It comprises a smaller fraction in the crust.

How many moles of neon are in 7.53x1023 atoms of Neon? How many moles of chromium are in 1.44x1024 atoms of Chromium? How many moles of boron are in 3.79x1024 atoms of Boron? The correct answer is D. 1.13 x 10^22 atoms are present in 0.378 g of neon. Avogadro's number (6.022 x 10^23) gives the ratio of representative particles per mole of substance. For every mole of substance, there are 6.022 x 10^23 representative particles present.
Since Neon is an inert gas, it also exists as a single atom in its molecular state. Therefore, one mole of Ne contains 6.022 141 79 (30) × 10^23 (Avogadro's Number) atoms of Ne.The three Neon isotopes are used for various purposes. Ne-22 is used for the production of the medical radioisotope Na-22. Ne-20 can be used for the production of F-18, although the route via O-18 is by far the most commonly used.
