1. The amount of neutrons and protons a molecule have determine a molecules “Molecular Weight”. An important part of working a laboratory involves making molar solutions. Using what you know about molar solutions how many grams of sodium chloride (MW 58.4) would you dissolve in 2 liters to make a 1M solution?

2. An ionic bond between two atoms is a transient bond formed as a result of electron transfer. What processes in the cell are modulated by the length and strength of these non-covalent bonds?
