Question

How many moles of nitrate are dissolved in water if 6.15 mole strontium nitrate dissolve?
***hint: how many nitrate ions are found in the compound?

Answer 1

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

Given data :

Moles of strontium nitrate = 6.15 moles

Ionization of Strontium Nitrate

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.
