Calculate % concentration of of solution prepared by dissolving 8.5 g of glucose (C6H1206) in 35 g of water24 %none of the other answers are correct1.35 %20.%4.1 %

Answer 1

- First, to calculate the % concentration of glucose in the solution, we need to add the 8.5g of glucose to the 35 g of water, to get the weight of the solution:

`\begin{gathered} \text{solution weight=8.5g + 35g} \\ \text{solution weight=43.5g} \end{gathered}`

- Second, we calculate the %w/w (weight/weight) with the solute weight and the solution weight:

- So,
