the answer is 332.25 grams
atoms definitions and I hope this helps
Answer:
1.26 g of Cu
Explanation:
Since we have to find the percentage of the given amount so...
Yield in grams = (Initial mass used / 100) x Percentage Yield
Yield in grams = (1.57 / 100) x 80.6 = 1.26 g of Cu
look at the atomic number using the periodic table. The Atomic number equals the amount of protons and the amount of protons equals the amount of electrons
The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.
