Alloy is a substance formed from the combination of two or more metals. It can be combinations of other elements also. To determine the chemical composition of an alloy (or any metal) are X-ray fluorescence spectroscopy (XRF) and optical emission spectroscopy (OES) are the two main methods used.  

How to find weight composition of an alloy?

Given data

The composition of alloy is:

CAg=94.1%, Ag=0.941C

Ccu=5.9%, Cu=0.059C

The atomic weight of Ag is: WAg=107.87g/mol

The atomic weight of Cu is: WCu=63.55g/mol

The percentage composition for Ag.

PCAg=CAgWAgCAgWAg+CCuWCu×100PCAg=CAgWAgCAgWAg+CCuWCu×100

Substitute the given value.

PCAg=0.941×107.87g/mol0.941×107.87g/mol+0.059×63.55g/mol×100

=96.43%PCAg

=0.941×107.87g/mol0.941×107.87g/mol+0.059×63.55g/mol×100

Thus main answer is =96.43%

The percentage composition for Cu.

PCCu=CCuWCuCAgWAg+CCuWCu×100PCCu=CCuWCuCAgWAg+CCuWCu×100

Substitute the given value.

PCCu=0.059×63.55g/mol0.941×107.87g/mol+0.059×63.55g/mol×100

=3.56%PCCu

=0.059×63.55g/mol0.941×107.87g/mol+0.059×63.55g/mol×100

Thus, main answer is =3.56%

Thus, the percentage composition of Ag is 96.43%96.43% and percentage composition of Cu is 3.56%3.56%.

So, the option (b) is correct.
