Flashcards in Stoichiometry Deck (7):
1

Mass Percent

Mass solute/Mass solution

2

Molarity (M)

moles solute/Liter solution

3

Conversion factors at STP

273 K and 1 atm
1 mole = 22.4 L

4

Standard State vs. STP

298 K is Standard state; STP = 273 K

Standard State is 1 atm, 298 K, and 1 molar concentration of all the reactions. It's used in Gibbs free energy

STP is simply a set of temperature atmospheric conditions.

5

molality (m)

moles solute/kg solvent

6

mole fraction (x)

moles of solute/total moles of all solute and solvent

7

parts per million (ppm)

(mass of solute/total mass of solution) x 10^6
