The mass of flask will be "69.4 g".
The given values are:
As we know,
→ [tex]Mass \ of \ Vinegar = Density\times Volume[/tex]
By putting the values, we get
→ [tex]= 1.05\times 76.2[/tex]
→ [tex]= 80.01 \ g[/tex]
hence,
→ [tex]Total \ mass = Mass \ of \ flusk +Mass \ of \ Vinegar[/tex]
or,
→ [tex]Mass \ of \ flusk = Total \ mass - Mass \ of \ Vinegar[/tex]
→ [tex]= 149.5-80.01[/tex]
→ [tex]= 69.4 \ g[/tex]
Thus the above answer is right.
