Answer:
The ratio of the number of atoms of gold and silver in the ornament is 197 : 1080.
Explanation:
Let the mass of silver ornament be x.
Mass of gold polished on an ornament = 1% of x= 0.1 x
Moles of silver =
Number of atoms =
Where : = Avogadro number
Moles of gold =
Silver atoms =
Gold atoms =
The ratio of the number of atoms of gold and silver in the ornament:
= 197 : 1080
Answer:
The correct answer is 372852.9 g.
Explanation:
First, we must look for the relationship between the masses in grams and pounds.
To get an approximate result, the relationship between pounds and grams found is:
1 lbs = 453.592 g
Now we must use this relationship as a conversion factor in the following way:
8.22 lbs * = 372852.9 g
The mass expressed in grams for 8.22 lbs is 372852.9 g.
Have a nice day!
