Answer:

mass = 6.56 grams

Explanation:

No of molecules = No of moles ×  Avogadro's constant

Similarly, number of moles = mass/ molar mass

∴

[tex]\text{number of molecules} = \dfrac{mass }{molar mass}}\times avogadro's \ no[/tex]

[tex]6.60*10^{22}}} = \dfrac{mass }{60.0 \ g/mol} \times 6.022 \times 10^{23}[/tex]

[tex]6.60*10^{22}}}\times 60.0 \ g/mol =mass\times 6.022 \times 10^{23}[/tex]

[tex]mass = \dfrac{6.60*10^{22}\times 60.0 \ g/mol}{6.022 \times 10^{23}}[/tex]

mass = 6.56 grams
