Silver Medal made up of 580g of Silver(Ag)

Bronze Medal made up of 444g of Copper(Cu) and 49g of Zinc(Zn)

The medals for the 2018 Winter Olympics are composed of gold, siliver, copper, and zinc metals. The masses of each component are shown in the picture below for the metals and metal alloys. Answetholloing questions about th THE WINTER OLYMPICS MEDALS medals. 1. What is the percent composition of gold in the gold medal? 2. What is the mass of the gold medal in pounds (bs? 3. What is the volume of the siver medal in militers (mL)?

Explanation / Answer

Total weight of gold model: 580+5=585

Percent composition of gold = 5/585 * 100= 0.85% w/w

2)1 kg/1000g=2.205 pounds

Hence 580g or 0.580g will be x

X= 0.580*2.205=1.2789pounds

3) assuming the silver is pure , the density will be 10.5g/cm3

Density = mass/volume

Hence 10.5=580/volume

Volume = 55.23 cm3= 55.23 ml
