The quantity of carbon tetrachloride, CClâ‚„ she will use to make her conversion is molar mass
Description of mole
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
How to determine the mole of CClâ‚„
- Mass of CClâ‚„ = 30 g
- Molar mass of CClâ‚„ = 12 + (35.5Ă—4) = 154 g/mol
- Mole of CClâ‚„ =?
Mole = mass / molar mass
Mole of CClâ‚„ = 150 / 154
Mole of CClâ‚„ = 0.974 mole
Thus, we can see that the molar mass of CClâ‚„ is needed to obtain the number of mole.
