Question

What is the concentration of a `5.00*g` mass of common salt, dissolved in water to make a `25*mL` volume of solution?

Answer 1

A common salt solution made from `5*g` of salt, with a volume of `25*mL`....?

Explanation:

`"Molarity"="Moles of solute"/"Volume of solution"`....and given my starting conditions we get....

`((5.00*g)/(58.44*g*mol^-1))/(25*mLxx10^-3*L*mL^-1)=3.42*mol*L^-1`

In you question you switched from common salt to unknown salt...and of course we cannot assess the concentration if we don't know the identity of the salt.....
