2. Read the buret volume and report your reading with the proper number of digits.
3. A sample of 45.0% v/v solution of ethanol in water has a volume of 115mL.
What volume of ethanol solute does the sample contain?
45% v/v
(Volume of ethanol / volume of solution )*100 = 45
= Volume of ethanol / 115 )*100 = 45
Volume of ethanol = 51.75 ml
If you have any questions please comment
If you satisfied with the solution please rate it thanks
