Question

determination of mass percentage of oil from different oil seeds

Answer 1

In order to determine the percentage of of oil from different oil seed there are various methods.  Differential techniques is use to determine the oil percentage by just weighing the seed first and then oil at last.

For the extraction of oil different methods used are
1) Mechanical extraction (i.e using mini-screw press method)
2)Solvent extraction method (like Soxhlet extraction method)
3) Super critical extraction ( advanced technique using CO2)

These methods helps to extract the oil then extracted oil is weighed to determine the percentage of oil from specific oil seed.

Answer 2

First, determine the weight of all the oil seeds of one type. Let this weight be X.

Now, extract oil from these seeds and determine the weight of the oil. Let this weight be Y.

To determine the mass percentage of oil from the oil seeds, divide the second weight by the first weight and multiply the result by 100. In other words, the mass percentage will be Y/X * 100.

Repeat the same process for each type of oil seed to determine the mass percentage of oil from different oil seeds.

Alternatively, if you want the cumulative mass percentage of oil, take the cumulative weight of all the oil seeds together. Similarly, mix oil extracted from all the seeds together and weigh the oil. Then, calculate the mass percentage as mentioned above.
