Given - Silver present: 95%

Weight of necklace: 15 gram

To find - Mass of silver in a necklace

Solution - As per the fact, sterling silver has a 95% concentration of silver. So, the necklace weighing 15 grams will have 95% mass as silver.

Therefore, 95% of 15 will be calculated to know the mass of silver.

Mass of silver = 95*15/100

Mass of silver = 14.25 gram

Hence, the mass of silver in a necklace weighing 15 grams is 14.25 grams.
