Answer the following:
A solution contains 78 \(g\) of salt in 231 of water \(mL\). Find out the concentration in terms of mass by volume percentage of the solution.
Mass of solute (salt) = \(g\)
Volume of solution = \(mL\)
\(m\) \ \(V\) \(\%\) = / ) x 100.
The mass by volume percentage \(=\) \(\%\)
