An atom has an average atomic mass of 63.5amu. 1 amu is equal to 1 gram per mole. So 63.5 amu is equal to 63.5 grams per mile or 63.5 g/mol. So the answer is Cu or Copper. Hope this helps. If it does, please mark as Brainliest.
Answer:
Percentage of gold = 84.6%
Explanation:
Suppose the jewelry has x g of gold and y g of silver
The mass of both is the total mass of the jewelry then:
x + y = 11.54
And as the problem says the total volume is the sum of both volumes.
volume = mass / density
Solving the system you get:
x = 9.764 g
y = 1.776 g
The percentage of gold in the jewelry is:
The enthalpy is the heat added to or lost in a system.
