The Atomic Mass of Copper is 63.5 grams One mole of any element has a mass equal to the atomic mass.
0.75 grams of Cu = x moles of Cu
63.5 grams of Cu = 1 mole of Cu
Set up a proportion and solve for x
Divide
0.75 / 63.5 = x /1
0.75 ÷ 63.5 = x

How many grams of copper will react to completely replace silver from 666mL of a 1.5M solution of silver nitrate?
To completely replace silver in the solution with copper, you would need an equal number of moles of copper to the moles of silver present. Calculate the moles of silver in the solution using the concentration and volume given. Then use the mole ratio between copper and silver to determine the moles of copper needed, and convert this to grams.
How many moles of copper sulfate are needed to make 2.50 Liters of 0.125 moles solution?
0.125 Molar solution! Molarity = moles of solute/Liters of solution Algebraically manipulated, Moles of copper sulfate = 2.50 Liters * 0.125 M = 0.313 moles copper sulfate needed ===========================
If you have 1.8 x 10 to the 23 atoms of copper how many moles of copper do you have?
The formula for converting is: atoms ÷ Avogadro's constant = # moles (1.8 × 1023) ÷ (6.02 × 1023)= 0.299 moles Cu

How many atom in 6.35 g of copper?
To find the number of atoms in 6.35 g of copper, you first need to determine the number of moles of copper present by dividing the mass of copper by its molar mass (63.55 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in that number of moles.

How many atoms of phosphorus are in 7.6 moles of copper phosphate?
There are 4 phosphorus atoms in one molecule of copper phosphate (Cu3(PO4)2). Therefore, in 7.6 moles of copper phosphate, there would be 7.6 moles x 4 atoms = 30.4 moles of phosphorus atoms.
How many moles of anhydrous copper sulfate is produced when 6.4 moles of hydrated copper sulfate is heated?
When hydrated copper sulfate is heated, it loses its water molecules to form anhydrous copper sulfate. Since the molar ratio between the two forms is 1:1, if 6.4 moles of hydrated copper sulfate is heated, 6.4 moles of anhydrous copper sulfate will be produced.
