Answer is: 79.8 grams of copper(II) sulfate.
N(CuSO₄) = 3.01·10²³; number of molecules.
n(CuSO₄) = N(CuSO₄) ÷ Na.
n(CuSO₄) = 3.01·10²³ ÷ 6.02·10²³ 1/mol.
n(CuSO₄) = 0.5 mol; amount of substance.
m(CuSO₄) = n(CuSO₄) · M(CuSO₄).
m(CuSO₄) = 0.5 mol · 159.6 g/mol.
m(CuSO₄) = 79.8 g; mass of substance.
M - molar mass.

The study of chemicals and bonds is called chemistry. There are two types of elements are there and these are metals and nonmetals.

The correct answer to the question is 79.8 grams of copper(II) sulfate.

What are moles?

  • The mole is the base unit of the amount of substance in the International System of Units.
  • It is defined as exactly 6.02214076×10²³ elementary entities, which may be atoms, molecules, ions, or electrons.

According to the question, The number of molecules will be = [tex]3.01*10^{23}[/tex]; a number of molecules.

[tex]n= \frac{number of molecules}{6.022*10^{23}}[/tex]

The number of moles will be after calculation will be:-

[tex]n=\frac{6.022*10^{23}}{3.01*10^{23}}[/tex]

Hence, the number of moles will be 0.5-mole amount of substance.

[tex]moles = \frac{mass}{molar\ mass}[/tex]

Mass will be is [tex]0.5 mol * 159.6 g/mol.[/tex]

Hence, the mass will be 79.8g mass of the substance.
