Answer:
A. 1.3
Explanation:
The density is defined as
[tex]Density=\text{mass}/\text{Volume}[/tex]Now in our case
mass = 65g
and
volume = 50 cm^3.
Therefore, the density is
[tex]\text{density}=65g/50\operatorname{cm}^3[/tex][tex]=1.3\frac{g}{\operatorname{cm}^3}[/tex]Hence, the density of the solution is 1.3 g / cm^3.
