Molarity = moles/Volume in Liters 

<span>We have volume, we need moles 
</span>molar mass of NaF = 42

<span>moles = mass/molar mass = 12.9 g/ 42 = 0.307 moles </span>

<span>Molarity =0.307 moles / 0.750 L </span>

<span>Molarity = 0.41M</span>

Acids are species with pH less than 7, while bases those with pH greater than 7. ... Using Arrhenius' definition, acids are those that produce the hydrogen ion when dissolved in water ( ) while bases produce the hydroxide ion ( ). These ions, when in water, act as charge carriers and can hence conduct electricity.

Acid–base reactions require both an acid and a base. ... For example, according to the Arrhenius definition, the reaction of B If inorganic, determine whether the compound is acidic.
