Answer:
The answer to your question is 1.2 moles of copper
Explanation:
Data
mass of copper = 75 g
moles = ?
Process
1.- Look in the periodic table for the atomic mass of copper.
Atomic mass = 63.55 g/mol
2.- Use proportions to determine the moles of copper in 75 g
63.55 g of copper -------------------- 1 mol
75 g of copper -------------------- x
Use cross multiplication
x = (75 x 1) / 63.55
x = 75 / 63.55
x = 1.18 moles ≈ 1.2 moles of copper
