Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Question

Find the % mass for NH3 and CU in the compound. Please help!

Suppose 0.3000 g of an blue coordination
compound was dissolved in water.
formula was not known, but Cu²+ and NH3 were
present in the compound.
The exact
Exactly 39.12 mL of 0.123 M HCI was needed to
titrate the NH3 that was present. Then, 24.40 mL of
