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

What is special about nitrogen and what is its function in the atmosphere
Vladimir79 [104]
Nitrogen makes up 70-80% of the atmosphere. If nitrogen weren't here, we wouldn't be able to breathe in oxygen because of the density of the air and because the air would then be toxic and flammable because there would be too much oxygen in the air. So with nitrogen, we are able to breathe safely. It makes it so we can breathe and keeps the atmosphere at a normal density.
