Molar mass ( CuSO₄) = 159.609 g/mol

159.609 g ----------------- 6.02 x 10²³ molecules
         ? g ------------------ 3.36 x 10²³ molecules

mass = ( 3.36 x10²³) x 159.609 / 6.02 x 10²³

mass = 5.36 x 10²⁴ / 6.02 x 10²³

mass = 8.90 g 

hope this helps!

Answer:

The mass of the given number molecules of copper sulfate 88.98 g.

Explanation:

Number of copper sulfate molecules =  \(3.36\times 10^{23}\)

Moles of copper sulfate : x

Number of molecules = Moles\(\times N_A\)

\(3.36\times 10^{23} =x\times 6.022\times 10^{23}\)

x = 0.5579 moles

Mass of 0.5579 moles of copper sulfate:

\(0.5579 mol\times 159.5 g/mol=13.38 g\)

The mass of the given number molecules of copper sulfate 88.98 g.
