Solution:

we have been asked to find

How many ounces of gold are in aa 14​-karat gold chain that weighs 2.5 ​ounces?

14 -Karat Gold means 14 parts of gold in the 24 parts of the Gold chain.

So the ratio of pure gold is [tex]\frac{14}{24} =\frac{7}{12} [/tex]

So the pure gold in 2.5 ​ounces of gold chain can be given as  below

[tex] Gold=\frac{7}{12}*2.5=1.458333[/tex]

Hence there is 1.5 Ounce of pure gold in the 14​-karat gold chain that weighs 2.5 ​ounces.
