Following the approach described above, the average molecular mass for this compound is therefore: Check Your Learning WebIt is important to note that a subscript following a symbol and a number in front of a symbol do not represent the same thing; for example, H 2 and 2H represent distinctly different species. H 2 is a molecular formula; it represents a diatomic molecule of hydrogen, consisting of two atoms of the element that are chemically bonded together. The … fnf playground coloring

3.3: The Mole and Chemical Formulas - Chemistry LibreTexts

WebHow many copper atoms are in 3.7 moles of copper? If one atomic mass unit is equal to 1.6606 times 10^ {-24} g, what is the mass in grams of 83549 atoms of Cu? Complete the following... WebThe mole (mol)is the amount of a substance that contains as many elementary entities (atoms, ions or molecules) as there are atoms in exactly 12 grams of 12C. 32 Molar mass is the mass of 1 mole of units (atoms/molecules) in grams. 33 1 mol of C contains 6.022 x 10 23 C atoms and has a mass of 12.01 g (molar mass ) M = molar mass in g/mol N WebFirst off, 3.4 / 342 = 0.01, not 0.001, so moles H = 0.22, not 0.022. Then you multiplied the erroneous 0.022 x 6.022 x 10^22. Avogadro's number = 6.022 x 10^23, not 10^22! So your final answer should be 1.3 x 10^23 H atoms (choice B). Your reasoning was right on, just a few math errors. 11 years ago greenville county building code residential
