- A solution is 555% solute by mass. If the molar mass of the solute is 86.68 gmol86.68\text{ }\frac{g}{mol}86.68 molg, and the solution has a molarity of 111 molar, what is the …
- We have a solution of table salt in water. What could we do to increase the concentration? What could we do to decrease the concentration?
- When a salt is dissolved in water, it dissociates. That is to say, it splits into it's component ions. NaCl→Na++Cl−NaCl \rightarrow Na^{+}+Cl^{-}NaCl→Na++Cl− If one mole of NaCl…
- The amount of ethyl alcohol in an alcoholic drink is typically expressed in percent ABV (alcohol by volume) or proof, where 1% ABV≈2 proof1\% \text{ ABV} \approx 2\text{ proof}1…
- Which is not a unit of concentration?
- 2 moles of salt are placed into a beaker, then water is added until the solution has a volume of 1 liter. 900 milliliters is then removed from the beaker, and the beaker is refi…

- Molality is a less common measurement of concentration, expressed in mol solute / kg total solution and abbreviated as m. If Alex drinks 200 0.5 L cold brew coffees, each with a…
- When CaCl2CaCl_{2}CaCl2 dissolves in water, it follows the reaction CaCl2→Ca++2Cl−CaCl_{2} \rightarrow Ca^{+} + 2Cl^{-}CaCl2→Ca++2Cl− If one mole of CaCl2CaCl_{2}CaCl2 is add…
