Title: How do I find moles and number of atoms when given an element? Post by: tommyo0729 on Sep 4, 2012 I am having trouble with my practice homework problems. I need to know how to find number of atoms when given moles and element and how to find the number of moles when given the number of atoms and the element.
Example Problems: 1. Element is Cr: Number of Atoms is 9.67 x 10^23............Find Moles 2. Element is Fe: Moles is 1.16 x 10^-5.........Find Number of Atoms Please explain. Thank you!

Title: How do I find moles and number of atoms when given an element? Post by: tommyboiazn23 on Sep 4, 2012 its simple mathematics as
1) 6.022 x 10^23 atoms = 1 mole then , 9.67 x 10 ^ 23 atoms = 1 x 9.67 x 10^23 / ( 6.022x 10^23) ............................. ................... = 1.606 moles 2) this one should try . its easy .then only u will understand |
