Calculate the p value of each ion indicated:

Nataliya [291]

27/208 = normality

12 x 10^-2 approx = normality

nw Ka = 14.3 x 10^-3

pKa = 3 - log 14

now, after getting the pKa put it in formula :
pH = pKa + log concn of ion/concn of salt and you'll get it

hope this helps

Mg + 2 AgNO₃ → Mg(NO₃)₂ + 2 Ag How many grams of magnesium nitrate, Mg(NO₃)₂, are formed when 9.87 moles of silver nitrate, AgNO

Aleksandr-060686 [28]

Mass of Magnesium nitrate formed : 731.86 g

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

Mg + 2AgNO₃ → Mg(NO₃)₂ + 2 Ag

moles of silver nitrate, AgNO₃ = 9.87

mole ratio AgNO₃ : Mg(NO₃)₂ = 2 : 1, so mol Mg(NO₃)₂ :

$\tt \dfrac{1}{2}\times 9.87=4.935$

mass of Mg(NO₃)₂(MW=148,3 g/mol) :

$\tt mass=mol\times MW\\\\mass=4.935\times 148,3\\\\mass=731.86~g$
