Choose the correct option. 13. So. Thus, helium is the smallest element, and francium is the largest. This time, even though the number of protons increases by a lot, the electron valence shells do not. Get 1:1 … Test Prep. Then, the bigger amount of oxygen is in the 0,0553 g of SO_3 where there is a bigger number of moles. Therefore, the number of atoms is 7.53 x 10 23. New questions in Chemistry. No of atoms in 1 gm of B =( 1/10.8 )* ( 6.023* 10^23) = 0.58 * 10^23 Also you can check as smaller the atomic mass , larger will be the number of atoms one year ago A) LiF B) NaCl C) CH4 D)MgF2. If you have 4 grams, you have 1/4 of a mole, but that means 5 atoms per molecule, so you end up with 1.25 * Avogadro's number of atoms. Sodium has a atomic mass of 23, so that means 23 g of sodium would be 1 mole (Avogadro number of atoms). Obviously, there are more oxygen atoms in SO_3. C) CH4. A) NaCl B) He C) H2O D) Li. Which ofhte following will have maximum number of C atoms ? 6.3k SHARES. The atomic weight of oxygen is 16, so one mole weighs 16 grams. NH3 = three H atoms per molecule * 1.5 moles = 4.5 moles of H atoms total. 1g Au (s) 1g Na (s) 1g Li (s) 1g Cl 2 (g) Advertisement Remove all ads. Atomic radius means the distance between the farthest electron and the center of the nucleus. = 1/23 mol of Na. Therefore, 0.125 × 10 23 molecules will contain 3 × 0.125 × 10 23 atoms = 0.376 × 10 23 atoms Thus, 1 g of oxygen , 1 g of oxygen molecule and 1 g of ozone will contain same number of oxygen atoms. 16O Q:-In a reaction A + B2 → AB2 Identify the limiting reagent, if any, in the following reaction mixtures. School Zayed University; Course Title BIO 202; Type. Equal mole of an element contains equal number of atoms. Geeze, NaCl has 1 mole of Na and 1 mole of Cl per mole of NaCl. 1:38 4.0k LIKES. Select one: A. 1 mol water B. Determine the empirical formula of an oxide of iron which has 69.9% iron and 30.1% dioxygen by mass. A.1g Au(s) B.1g Na(s) C. 1g Li (s) D. 1g Cl2(g) 1 See answer kksanthoshdr8387 is waiting for your help. C) H2O. 1 mole (6.02 *10^23 atoms) of any element will weigh the atomic mass of the element in grams. It's C because Nitrogen would have the least molar mass and therefore take more atoms to make up the 36 g. 1 mol of C-12 has a mass of 12 g, H around 1 g. 1 mol of N2 has a mass of about 28 g, so it would take about 1.29 mol to have a mass of 36 g. You don't even have to bother with krypton, because the atoms are too heavy. Again, this is due to the effective charge at the nucleus. How to solve: Which of the following has the largest number of chlorine atoms? MCQ. Periodic Trends of Atomic Radius. Consider the hydrate FeSO4 • 7H2O. Pages 7 This preview shows page 2 - 4 out of 7 pages. Hence, 1 g of Li (s) will have the largest number of atoms. So 1 mole of chlorine would weigh 35.5g. Hence out of . The other trend of atomic radius or atom size occurs as you move vertically down an element group. on condition that Avogadro's sort does not substitute and you in simple terms ought to %. ii. A. 1g of Li contains atoms = 6.022 x 10 23 /7 *1= 86.0 x 10 21 atoms (iv) Gram atomic mass of Cl = 71 Or 71g of Cl contains atoms = 6.022x10 23. Hydrogen (H) Which of the following notations represents a molecule? a)Cs b) At c)Zn d)Hg e)Mn. The largest producer of sugarcane in India is - 📌 2.6k VIEWS. Thus, 1 g of Li has the largest number of atoms. Which element in the formula has the largest number of atoms? Hence 1 g Li(s) has the largest number of atoms Hope you found this question and answer to be good. 600+ SHARES. 1g of Li = 1/7 mol of Li. So that is 2 moles of atoms per mole of NaCl. - Chemistry. Aspartame is an artificial sweetener; its formula is C13H16N2O5. Thus there are 6.023 X 10 23 atoms of copper in 63.5g of copper. Which of the following contains the largest number of atoms?
