Calculate the number of molecules of Sulphur (\\[{S_8}\\]) present …
WebSolution. To calculate the percent composition, the masses of C, H, and O in a known mass of C 9 H 8 O 4 are needed. It is convenient to consider 1 mol of C 9 H 8 O 4 and use its molar mass (180.159 g/mole, determined from the chemical formula) to calculate the percentages of each of its elements: % C = 9 mol C × molar mass C molar mass C 9 H ... Web24 jan. 2024 · Now we calculate the total number of molecules in this amount of O2. = 0.1 * 6.022 * 10^ (23) Now we know that, one molecule of O2 has 2 atoms of oxygen and 1 atom of oxygen contains 8 electrons. So total no of electrons in 2 atoms/1 molecule are 16. For total no of electrons in 3.2 g O2 are =. 6.022 * 10^ (22) * 16. Hope it helps. bling sofa pillows on couch
Which of the following is the particle of gas?
Web1 mol of 12C atoms = 6.02 x 1023 atoms = 12 g . Or, 6.02 x 1023 atoms of 12C have mass = 12 g . Therefore, 1 atom of 12C will have mass = 12 x 1/6.02 x 10. 23 = 1.9927 x 10-23. g . 1.31. How many significant figures should be present in … WebUnder normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Molar mass of S atom=32g/mol. Hence, molar mass of Sulphur molecule (S8) is: 8×32 mol/g=256 mol/g. 2. From the chemical formula, we have one Pb atom, so the atomic mass would just be 207.2 g/mol. 3. WebSulfur, just ‘S’ by its lonesome, has a molecular weight of 32 g/mol. As such, then. However, sulfur tends to exist as S8 (aka octasulfur, Octasulfur - Wikipedia ), shown … blings of leon
