How do you convert grams to moles?
Divide by the molar mass
300
What rule states that atoms tend to gain, lose, or share electrons to achieve a full set of 8 valence electrons?

300
What bond angle is associated with a linear molecular geometry?
180°

Why do ionic compounds conduct electricity when dissolved in water but not as solids?
In water, the ions are free to move, allowing the flow of electricity, whereas in solids, ions are locked in place.
