The karat is a dimensionless unit that is used to indicate the proportion of gold in a gold-containing alloy. an alloy that is one karat gold contains a weight of pure gold that is one part in twenty-four. what is the volume of gold in a 14.0-karat gold necklace whose weight is 1.25 n?

Volume,

Explanation:

It is given that, an alloy that is one karat gold contains a weight of pure gold that is one part in twenty-four.

14 karat of gold contains a weight of pure gold is,

The necklace contains 58% of gold, the weight of gold is :

The mass of gold is,

Let V is the volume of fold in 14 karat. Using the formula of density to find it as :

d is the density of gold,

So, the volume of fold necklace is . Hence, this is the required solution.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
