A solution is created by dissolving 11.5 grams of ammonium chloride in enough water to make 255 mL of solution. How many moles o

Nata [24]

Answer:

<h2>The no. of moles present in one liter solution is 0.843</h2>

Explanation:

Mass of ammonium chloride = 11.5 gm

Molar mass of ammonium chloride = 53.491 gm

No. of moles

$N = \frac{mass}{molar \ mass}$

$N = \frac{11.5}{53.491}$

N = 0.215 moles

$Molarity= \frac{N}{volume}$

$molarity = \frac{0.215}{0.255}$

M = 0.843 M

Thus the no. of moles present in one liter solution is 0.843
