The total mass of the mixture will be "958.5 g".
According to the question, the density of both the mixtures will be:
The volume of both the mixtures,
As we know,
→ [tex]Density = Mass\times Volume[/tex]
now,
→ The mass of Ethanol will be:
= [tex]0.785\times 100[/tex]
= [tex]78.5 \ g[/tex]
→ The mass of Benzene will be:
= [tex]0.880\times 1000[/tex]
= [tex]880 \ g[/tex]
hence,
→ The total mass will be:
= [tex]78.5+880[/tex]
= [tex]958.5 \ g[/tex]
Thus the above answer is correct.
