How many atoms are in a gram
WebAvogadro's number is the ratio of the mass of 12 grams of carbon-12 to the mass of 1 atom of carbon-12 measured in grams. Or, a little easier to understand, Avogadro's number is the ratio of 1 gram to 1 atomic mass unit but with the atomic mass unit expressed in grams. Thus, Avogadro's number has been measured to be 6.022141×10²³. WebSep 3, 2024 · By looking at a periodic table, we can conclude that the molar mass of the element lithium is 6.94g, the molar mass of zinc is 65.38g, and the molar mass of gold is 196.97g. Each of these quantities contains 6.022 × 10 23 atoms of that particular element.

WebSorted by: 9. Both approaches are correct. Avogadro's number is 6.02214129 × 10 23 and represents the number of carbon-12 atoms in 12 grams of unbound carbon-12 in the ground electronic state. 12 grams / 6.02214129 × 10 23 = 1.9926467 × 10 − 23 grams. The unified atomic mass unit (u) is 1.660538921 × 10 − 24 grams.
WebSep 7, 2024 · Using a calculator, divide the number of grams by the molar mass. The result is the number of moles in your element or compound. [9] For example, imagine you have 2 g of (NH 4) 2 S and you want to convert it to moles. The molecular mass of (NH 4) 2 S is 68.17g/mol. Divide 2 by 68.17, and you have 0.0293 moles of (NH 4) 2 S. Community Q&A … WebJul 25, 2024 · Each gram of chlorophyll contains 0.0268 g of Mg, atomic weight 24.3. Number of moles in this weight of Mg: (.0268 g) / (24.2 g mol –1) = 0.00110 mol Number of atoms: (0.00110 mol) × (6.02E23 mol –1) = 6.64 × 10 20 Is this answer reasonable?
