Answer 1

Explanation:

the amount of space that a substance or object occupies, or that is enclosed within a container.

Answer 2

$\huge\mathfrak\red{Answer!!}$

__________________________________

their is insufficient data in question

⚠️The Volume Should be 3L

__________________________________

$\huge\red{Given!!}$

Volume :- 3L

Weight of Copper sulphate:- 80g

Molecular weight of Copper Sulphate:- 159g

$\huge\red{Solution!!}$

Number Of moles :-

$= \frac{weight}{molecular \: weight}$

$= \frac{80}{459}$

$= 0.5 \: moles$

Molality :-

$= \frac{number \: of \: moles}{volume \: of \: solution}$

$= \frac{0.5}{3}$

$= 0.16666667$
