Question

If an alloy is formed that is 50 mol% silver and 50 mol% gold, what is the karat number of the alloy?

Answer 1

Karat number for the alloy = 12

Step-by-step explanation:

Given:

Mol% gold = 50

Mol% silver = 50

To determine:

The karat number of the alloy

Step-by-step explanation:

A Karat number is a parameter which is used to describe alloys containing gold based on the % gold in the alloy.

The corresponding formula is:

`Percent Gold = (K)/(24)*100`

where K= Karat number

`K = (Percent Gold * 24)/(100)=(50*24)/(100)=12`

Answer 2

Answer : 12 karat

Explanation : When pure gold is considered to be 24 karat then if its 50 mol% silver and 50 mol% silver then using karat scale calculation;

Karat/24 X 100 = 50 mol% (for gold) in alloy

So, Karat = (50 X 24) / 100 = 12 karat.

Hence the alloy will be of 12 karat.
