Respuesta :

 3.36 x 10^23 molecules x (1 mole/6.02 x 10^23 molecules) x (160 g/1 mole) 
 molar mass of a copper  
3.36/6.02x160 
copper sulphate cuso4weigh is 89.3g
this is the right equation
hope it helps

Answer: The mass of copper(II)sulfate are, 89.6 grams

Explanation: Given,

Molecules of [tex]CuSO_4[/tex] = [tex]3.36\times 10^{23}[/tex]

Molar mass of [tex]CuSO_4[/tex] = 160 g/mole

First we have to calculate the moles of [tex]CuSO_4[/tex].

As, [tex]6.022\times 10^{23}[/tex] number of [tex]CuSO_4[/tex] atoms present in 1 mole of [tex]CuSO_4[/tex]

So, [tex]3.36\times 10^{23}[/tex] number of [tex]CuSO_4[/tex] atoms present in [tex]\frac{3.36\times 10^{23}}{6.022\times 10^{23}}=0.56[/tex] mole of [tex]CuSO_4[/tex]

Now we have to calculate the mass of [tex]CuSO_4[/tex]

[tex]\text{Mass of }CuSO_4=\text{Moles of }CuSO_4\times \text{Molar mass of }CuSO_4[/tex]

[tex]\text{Mass of }CuSO_4=(0.56mole)\times (160g/mole)=89.6g[/tex]

Therefore, the mass of copper(II)sulfate are, 89.6 grams
