WebScientist analyze the rock for these two elements and find that the total mass of uranium in the rock is 2.40 g, while the amount of lead is 1.11 g. How old is this rock? Solution: 1) Determine moles of U-238 and Pb-206: Assume 240. g of U-238 and 111 g of Pb-206. moles U-238 ---> 240. g / 238.0508 g/mol = 1.00819 mol WebThe atoms to mole are totally based on the Avogadro’s number which is a numerical constant. So: 6.0221415E+23 atoms = 1 Mole atoms= 1 Mole/6.0221415E+23 The general atoms to moles formula is : Number of atoms= Mole/Avogadro’s Number Where: 6.0221415E+23= 6.022140857 x 10^23 How to Convert Moles to Atoms?
Using the generic expression to convert g to atoms: Number of Atoms = (Given Mass/Molar Mass) * Avogadro’s Number. Number of Atoms = (78/40.078) * 6.02 * 10^{23} Number of Atoms = 1.9462 * 6.02 * 10^{23} Number of Atoms = 1.171 * 10^{+24} For further verification, you can let this grams to atoms … See more Whether you are going to convert grams to atoms or vice versa, you must have a sound knowledge of the Avogadro’s Number. So let’s define this chemical term first: See more If we rearrange the above expression, the resulting one is can be used to convert atoms to grams and is as below: See more In chemistry, carrying out various to and fro conversions makes the calculations very easy.
