1) Particles→ Grams
- To find the mass of the molecule, another step is added to the equation from last time.
- Ex: You want: 7.49x 10^21 atoms of Colbalt into grams,
6.022 x 10^23 1 mole
* the grams is the atomic mass of Cobalt
2) Grams → Particles
- From the example above, the placement of 6.022 x 10^23 and the grams are swapped when converting grams→particles.
- Ex: You want the number of particles in 6.24 grams of Phosphorous.
31.0g 1 mole
* Please remember that significant figures always applys to the answers!
