Unified mass (u) of :-

- Cu [Copper - Cyprus] =
**6****3****.****5****u** - N [Nitrogen] =
**1****4****u** - O [Oxygen] =
**1****6****u**

**∴**** ****M****a****s****s****:****-**

63.5 u + [14 u + 16 u × 3] × 2

= 63.5 u + (14 u + 48 u)2

= 63.5 u + (62 u)2

= 63.5 u + 124 u

= 187.5 u **(****Solutio****n****)**
