PLEASE EXPLAIN TOO!

(Include an explanation on how to solve using 6.02 x 10^23. How to set up the problem is what I’m confused about)

Answer 1

Testosterone molecules : 2.11 x 10¹⁵

Further explanation

The mole is the number of particles(atoms,molecules,ions) contained in a substance

1 mol = 6.02.10²³  particles

Concentration : 3.5.10⁻⁹ M

$\tt M=\dfrac{mol\times 6.02\times 10^{23}}{L}\Rightarrow \dfrac{molecules}{L}$

$\tt M=\dfrac{3.5\times 10^{-9}\times 6.02\times 10^{23}}{L}\\\\M=\dfrac{2.107\times 10^{15}}{L}$
