Answer:

30.28 grams

Step-by-step explanation:

In order to find the answer we need to consider that:

X%=X/100 where 'X' represents the solute.

So, because we have a 10% solution then:

10%=10/100 which can be written as:

10/100=20/200 which means that there is 20 mL of mannitol for each 200 mL of solution, but, considering the density of mannitol ([tex]1.514 gr/cm^3[/tex]) we obtain:

[tex]\frac{20mL}{200mL}*\frac{1.514gr}{cm^3}*\frac{1cm^3}{1mL}=\frac{30.28gr}{200mL}[/tex]

In conclusion we have 30.28 grams of mannitol.
