Answer: 813.1\times 10^{23} atoms.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

1 molecule of C_2H_6O contains = 9 atoms

1 mole of C_2H_6O contains = 9 \times 6.023\times 10^{23}=54.21\times 10^{23} atoms

Thus 15 moles C_2H_6O contains =\frac{54.21\times 10^{23}}{1}\times 15=813.1\times 10^{23} atoms.

Thus the answer is 813.1\times 10^{23} atoms.

1 mole = 6.22 x 10^23 molecules (Avogadro's number)
15 moles x (6.22 x 10^23) = 9.33 x 10^24 atoms

Based on the chemical formula and state of matter, which of these substances will conduct electricity?
Sergeu [11.5K]

Answer:

CuSO4(aq)

Explanation:

The aqueous form of copper sulfate will conduct electricity.

The Solid form will not be a good conductor.

C₅H₁₂ will not conduct electricity

CO₂ will not conduct electricity

  • Copper sulfate is an ionic compound
  • In aqueous solutions or molten forms, ionic compounds can conduct an electric current using free mobile ions as carriers.
  • This way, they are electrolytes.
  • In solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.
