Ammonium phosphate ((nh), po) is an important ingredient in many fertilizers. it can be made by reacting phosphoric acid (ti, po.) with ammonia (nh) what mass of ammonium phosphate is produced by the reaction of 7.5 g of ammonia? be sure your answer has the correct number of significant digits.

22.35 g of  (NH₄)₃PO₄ will be produced by 7.5 g of ammonia.

Explanation:

H₃PO₄ + 3NH₃  → (NH₄)₃PO₄

H₃PO₄: 98 g/mol

NH₃: 17 g/mol

(NH₄)₃PO₄: 149 g/mol

17 g NH₃ 1 mol

7.5 g NH₃ x

  x = 0.44 mol NH₃

3 mol NH₃ 1 mol (NH₄)₃PO₄

0.44 mol NH₃           y

     y = 0.15 mol (NH₄)₃PO₄

1 mol (NH₄)₃PO₄ 149 g

0.15 mol (NH₄)₃PO₄    z

          z = 22.35 g (NH₄)₃PO₄

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
