The number of molecules in a mole of a substance is the same. One mole of any substance contains 6.023 x 10 raised to the power 23.
So one mole of O2 has 6.023 x 10(23) Oxygen molecules,
One mole of water contains 6.023 x 10(23) H2O molecules, and so on.
Prominent copper sulfide minerals include Cu2S (chalcocite) and CuS (covellite).
Answer:
2.4 E-7 Kg/mL = 2.4 E5 μg/dm³
Explanation:
⇒ 2.4 E5 μg/dm³ * ( 1 E-6 g/μg ) * ( 1dm³/L ) * ( L/1000mL ) * ( Kg/1000g )
⇒ 2.4 E5 μg/dm³ = 2.4 E-7 Kg/mL
