Best ResponseYou've already chosen the best response.0Stoichiometry has a fancy name but it's very easy. Just like \[\frac{ 1 }{ 2 }*\frac{3}{3} = \frac{3}{6} \] You are multiplying your value by 1, because the value of numerator equals the denominator. And just keep doing it so units cancel out to the ones you want to result to. 2.54 cm = 1 inch and you keep canceling the cm until you get in^3 (and not 1/in^3)

Best ResponseYou've already chosen the best response.0It's correct. If you have cm in the numerator and multiply it by something that has cm in the denominator, the cms cancel out.
