At STP, it is at 273 K and 1.00 atm.
Use PV=nRT to and solve for n (number of mol of N2)
1.00 atm • 4.40L / 0.08206 Latm/molK • 273 K = 0.196 mol N2
There are two mol of N2 for every two mol of NH4NO2 (the number of mol of both are equal)
Find the molar mass of NH4NO2 = 64.1 g
Multiply the number of mol by the molar mass
0.196 mol • 64.1 = 12.6 g NH4NO2

Answer is: ion product for strontium chromate is 3·10⁻⁵.<span>
Balanced chemical reaction (dissociation) of
strontium chromate:
</span>Sr²⁺(aq) + CrO₄²⁻(aq) → SrCrO₄.<span>
Qsp(</span>SrCrO₄) = c(Sr²⁺)·(CrO₄²⁻).<span>
c(</span>Sr²⁺) = 2.00·10⁻² M.
c(CrO₄²⁻) = 1.50·10⁻³ M.
Q = 2.00·10⁻² M · 1.50·10⁻³ M.
Q = 0.00003 = 3·10⁻⁵ M².
