Answer to Question #137840 in Organic Chemistry for Zuheila

Question

how many particles are in 2.66 of cu atoms?

Answer 1

 mass of cu atoms = 2.66 g .

moles of cu atoms = 2.66 / 63.5 = 0.04188 mol .

number of atoms = moles of cu atom * 6.02 * 10^23 = 0.0418 * 6.02 * 10²³ .

= 0.2516 * 10^23 .

=

2.5 * 10^22 atoms .
