Answer:
25 milliliters
Step-by-step explanation:
Given:
volume of sample = 100 ml
Syrup present in sample = 6.55 g per 20 mL
Therefore in 100 mL, amount of syrup present = [tex]\frac{\textup{6.55}}{\textup{20}}\times100[/tex]
or
amount of syrup present in 100 mL sample = 32.75 grams
Now,
Specific gravity of the syrup = 1.31
also,
Specific gravity of the syrup = [tex]\frac{\textup{Density of syrup}}{\textup{Density of water}}[/tex]
or
1.31 = [tex]\frac{\textup{Density of syrup}}{\textup{1 g/mL}}[/tex]
or
Density of syrup = 1.31 g/mL
also,
Density = [tex]\frac{\textup{Mass}}{\textup{Volume}}[/tex]
therefore,
1.31 = [tex]\frac{\textup{32.75}}{\textup{Volume of syrup in the sample}}[/tex]
or
Volume of syrup in the sample = [tex]\frac{\textup{32.75}}{\textup{1.31}}[/tex]
or
Volume of syrup in the sample = 25 milliliters
