To convert moles of a substance into the number of representative particles you will always multiply the number of moles of that substance by
- 1.5 x 1023
- 3 X 1023
- 4.5 X 1023
- 6 X 1023
- 1.2 X 1024
In order to convert from grams of a substance into moles of that substance you will need to
- divide the number of grams by the molar mass of that substance with the answer being moles of that substance.
- multiply the number of grams by the molar mass of that substance with the answer being grams of that substance.
- multiply the number of grams by the molar mass of that substance with the answer being moles of that substance.
- multiply the number of grams by the square root of the molar mass of that substance with the answer being moles of that substance.
