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.

Answer:

Karat number for the alloy = 12

Explanation:

<u>Given:</u>

Mol% gold = 50

Mol% silver = 50

<u>To determine:</u>

The karat number of the alloy

<u>Explanation:</u>

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 = \frac{K}{24}*100

where K= Karat number

K = \frac{Percent Gold * 24}{100}=\frac{50*24}{100}=12
