Answer:

5.66%

Explanations:

The formula for calculating the percent mass/volume of a solution is expressed as:


\%m\text{/}v=\frac{mass\text{ of solute\lparen g\rparen}}{mass\text{ of solution \lparen g\rparen}}*100

Given the following parameters

Mass of solute = 30000mg = 30g

Mass of solvent = 0.5litres = 500g

Mass of solution = 30g + 500g = 530g

Substitute the parameters into the formula


\begin{gathered} \%m\text{/}v=(30g)/(530g)*100 \\ \%m\text{/}v=(300)/(53) \\ \%m\text{/}v=5.66\% \end{gathered}

Hence the percent mass/volume of a solution is 5.66%
