Answer:
The weight/weight % or percent by mass of the solute is 1.04g.mL
Explanation:
We assume, (i) that the solvent is water, and (ii) that dissolution occurs without change in volume.
So given the standard density of water, the mass of the solution is simply,
(4.87+86.4)g
For solution, [tex]\frac{mass}{volume}=density[/tex]
= [tex]\frac{4.87+86.4g}{86.4mL}[/tex]
= 1.04 g. mL
Because nitrate salts are soluble stuff, you could get significantly higher solution densities if you dissolved more salt (volume change would be fairly negligible).
