The correct answer will be "4.60 g".
Explanation:
The given values are:
Volume of Butane = 7.96 mL
Density = 0.579 g/mL
As we know,
⇒![Mass \ of \ Butane = Density\times Volume](/tpl/images/0685/6419/92b79.png)
On putting the estimated values, we get
⇒![=0.579\times 7.96](/tpl/images/0685/6419/f8e20.png)
⇒![=4.60 \ g](/tpl/images/0685/6419/3d222.png)
