Recall,

$% w / v = \frac{g}{100 mL}$ $%w"/"v = "g"/(100"mL")$

$5.0 %$ $5.0%$ w/v glucose has $5.0 g$ $5.0"g"$ glucose per $100 mL$ $100"mL"$ of water.

Hence,

$1500 mL \cdot \frac{5.0 g}{100 mL} \approx 75 g$ $1500"mL" * (5.0"g")/(100"mL") approx 75"g"$

of glucose are in the solution, given your data.
