how to mole
Calculate the number of moles in the following mass: 12.34 gAu
Given: 12.34 g Au
Need: Moles
Unknown: Au atomic mass= 196.967g Au
1 mol
12.34g Au | 1 mol || 6.155 mol Au
| 196.967g A ||
*First what you have to do is find your given
*then you need to figure out what the question is wanting you to find: need
*then what your unknown is (which is what you are using to solve for your need)
*then you set your equation up and put your given in the top left box
*you figure out if you are looking for moles or mass and then put them in the correct box
* then you have to solve for your equation
*lastly you put your equation with the right # of Sig Figs
