Let's remember the definition of a m/v% concentration:


Concentration=\frac{\text{Solute mass}}{Solution\text{ Volume}}\cdot100

In this question, we're given that:


\begin{gathered} \text{percentage}=(5.50m)/(v) \\ Solution_{\text{ }}volume=205ml \end{gathered}

What we're going to do to find the solute mass, is to solve the equation for it:


\text{solute mass = (}(((5.50g)/(ml))(205ml))/(100))=11.275g

Therefore, there are 11.275g of glucose in the solution.
