ankoles [38]

Answer:

$n_{NH_3}=0.18molNH_3$

Explanation:

Hello,

In this case, the undergoing chemical reaction is:

$H_3PO_4(aq)+3NH_3(l)\rightarrow (NH_4)_3PO_4$

In such a way, considering the 3 to 1 molar relationship between ammonia and ammonium phosphate, the moles of ammonia result:

$n_{NH_3}=0.060mol(NH_4)_3PO_4*\frac{3molNH_3}{1mol(NH_4)_3PO_4}\\n_{NH_3}=0.18molNH_3$

Best regards.
