How many moles of nitrate are dissolved in water if 6.15 mole strontium nitrate dissolve?
pashok25 [27]

The number of moles of nitrate dissolved in water if 6.15 mole of strontium nitrate is :   12.3 moles

<u>Given data :</u>

Moles of strontium nitrate = 6.15 moles

<h3>Ionization of Strontium Nitrate </h3>

When strontium nitrate ( Sr(NO_{3} )_{2} ) is placed in water it will dissociates into its ions because strontium nitrate is an ionic compound.

Next step : Represent the ionization of strontium nitrate

Sr ( NO_{3} )_{2}  (aq) --- > Sr^{2+} (aq)  + 2NO_{3} ^{-} (aq)

From the Stoichiometry of the chemical reaction

I mole of strontium nitrate =  2 moles of Nitrate ions

6.15 mole of strontium nitrate = 2 * 6.15

                                                 = 12.3 moles of Nitrate

Hence we can conclude that The number of moles of nitrate dissolved in water if 6.15 mole of strontium nitrate is :   12.3 moles.
