Question

How many atoms of copper does the fitting contain?

A. Calculate the mass of copper.
B. Use Avogadro's number.
C. Determine the number of moles.
D. Assess the atomic weight of copper.

Answer 1

To determine the number of Cu atoms in the fitting, calculate the mass of copper and use Avogadro's number.

Step-by-step explanation:

The number of Cu atoms in the fitting can be determined by following a two-step computation:

For example, if the mass of copper in the fitting is known, you can use the molar mass of copper (63.54 g/mol) and Avogadro's number (6.02 × 10^23 atoms/mol) to find the number of Cu atoms in the fitting.
