The ionic compound, (NH₄)₂SO₄, will fully dissolve in water. If 15.16 g is dissolved in water to give a final volume of 402.0 mL, then find the following ion concentrations.

The concentration of the NH₄⁺ is:

The concentration of the SO₄^2- is:

Answer 1

Molar mass of (NH4)2SO4= 132.154 g/mol

Moles of (NH4)2SO4 $=\frac{15.16}{132.154}=0 .115mol$

$Molarity = \frac{0.115}{0.402}=0.29M$
