Concentration

[Melissa Solis 1H]

I was wondering why the concentration had to be positive? I'm not sure if I missed it during lecture, thanks!

Concentration is moles/liters, and we can't have a negative amount of moles or a negative volume (liters). Thus, the numerator and denominator will always be positive so concentration will always be positive. Hope this helps!

I believe concentrations can't be negative because they measure how much of a substance is present. So if there was none of something, then the concentration would just be 0, not anything in the negatives.

Concentrations cannot be negative because it is defined by moles/L. As it is impossible to have a negative number of moles or a negative number of L, the concentration must be positive.

Since concentration has moles/liter as its units, you cannot have a negative value. Hope this helps!

[Charmaine Ng 2D]

Concentration is a measurement of moles/Liter, and since you can't measure negative moles or negative Liters of something, it's not possible for concentration to be negative!

[Isabella Cortes 2H]

Concentrations cannot be negative since it is moles divided by liters and you can't measure negative amounts of either.

[Pranav Daggubati 3C]

You cant have negative moles of something, it just doesn't make sense. Concentration is moles/liters, so either of the two things have to be negative for a negative concentration, which is impossible.

The concentration has to be positive because any concentration less than 0 does not exist, 0 concentration means we do not have anything.

[Chance Herbert 3A]

A concentration or Molarity is the number of moles per Liter. It is not possible to have a concentration that is less than zero because this would imply that it is possible to have a negative number of moles or liters.

[Armen_Isayan_2L]

It is evident that concentrations cannot be deemed negative since it is defined by moles, you cannot have a negative mole per litre. Hence, concentrations are positive.

The values of volume and moles can never be negative so the ratio of the two (concentration) can also never be negative.

[Andy Hernandez]

Concentration is in moles/liters. We can't have a negative amount of moles or a negative volume so it's positive
