Answer:
0.417 mol could be extracted from a medal that weighs 115 grams
Explanation:
Our Olympic medal weighs 115 g and we know that 71.5% is gold so how much from this medal is gold?
100 % ____ 115 g
71,5 % ____ 82.22 g
Molar mass of Au is 196.97 g/m
Mass / Molar mass = Moles
82.22 g / 196.97 g/m = 0.417 moles
Kinetic energy=Ek
Ek=(1/2)mv²
Ek=480 J
v=8 m/s
mass=?
Ek=(1/2)mv²
480 J=(1/2)m(8 m/s)²
480 J=(32 m²/s²) m
m=(480 J)/(32 m²/s²)=15 kg
answer: the mass of the object is 15 kilograms.
