0.206 moles will contain 0.206 moles x 6.022 × 10^23 atoms which is equivalent to 1.240 x 10^23 atoms.
<h3>Total atoms in a compound</h3>
Given the following parameters
- Mass of Cu2s = 32.8 grams
Get the number of moles
Moles = 32.8/159.16 g/mol
Moles of Cu2S = 0.240moles
Since 1 molecule of atom = 6.02 * 10^23 molecules
Hence 0.206 moles will contain 0.206 moles x 6.022 × 10^23 atoms which is equivalent to 1.240 x 10^23 atoms.

Answer: B
<u>Explanation:</u>
x² - 8x + 19
a=1 b=-8 c=19
Use the Quadratic formula to find the solutions for x:
= 4 ± i√3
Solutions are: Factors are:
x = 4 + i√3 x - (4 + i√3) = 0
x = 4 - i√3 x - (4 - i√3) = 0
