Answer: The mass of given amount of molecules of copper sulfate is 89.054 grams.
Explanation:
According to mole concept:
1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of molecules.
The mass of 1 mole of copper sulfate = 159.609 grams
As, [tex]6.022\times 10^[23}[/tex] number of molecules have a mass of 159.609 grams.
So, [tex]3.36\times 10^{23}[/tex] number of molecules will have a mass of [tex]\frac{159.609g}{6.022\times 10^{23}}\times 3.36\times 10^{23}=89.054g[/tex]
Thus, the mass of given amount of molecules of copper sulfate is 89.054 grams.
