What is the density of a solution composed of #189*mL# of water, and #54*g# of salt?

Well, clearly, the masses are additive.....

Explanation:

And given that water has #rho_"density"=1.0*g*mL^-1#, we have a mass of (i) #189*mLxx1.0*g*mL^-1=189*g# with respect to water, and #54*g# with respect to salt, we gots....

#(54+189)*g=243*g# in total.

Given that the volume of the liquid would change marginally upon dissolution of the salt, can you tell us the density of the solution?

Remember, #rho_"density"="Mass of solution"/"Volume of solution"#, the which would give us an answer in #g*mL^-1#.
