How many moles is 125 g CuO2?

1.31moles

Explanation:

Given parameters:

Mass of CuO₂  = 125g

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we use the expression below:

   Number of moles  =  

Molar mass of CuO₂  = 63.6 + 2(16) = 95.6g/mol

So;

 Number of moles  =   = 1.31moles

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
