Answer:
56 g of glucose
Explanation:
We can find the mass of glucose used as follows:
[tex] \%_{m/m} = \frac{m_{s}}{m_{sol}}\times 100 [/tex] (1)
Where:
[tex]m_{s}[/tex] is the solute's mass =?
[tex]m_{sol}[/tex] is the solution's mass = 2000 g
% (m/m)= 2.8 %
By solving equation (1) for [tex]m_{s}[/tex] we have:
[tex] m_{s} = \frac{\%_{m/m}*m_{sol}}{100} = \frac{2.8*2000 g}{100} = 56 g [/tex]
Therefore, you used 56 g of glucose to make 2000 g of a solution of glucose in water.
I hope it helps you!
