Assuming you have the starting weight of unextracted material you can measure the weight the produced oil and calculate weight %. If you want only the % in the algae, you need to adjust the statring load for free water, the water the algae was grown in. If it was dehydrated prior to extraction this is not necessary. Also dependent of the oil extraction method (i.e, if it was pyrolytic) you may need to account for volatile oil loss, and possibly coking.

Abhishek Kumar

Indeed, it is feasible to ascertain the oil yield % based on the amount of algal oil that has been extracted, such as the specific quantity of 6.5 ml specified. However, in order to precisely determine the percentage of oil output, you must other information:

1. Density of Algal Oil: Determine the density of the algal oil, usually expressed in grams per millilitre (g/ml). This number enables the conversion of the volume (in millilitres) of algal oil to its corresponding mass (in grams).

2. Quantify the Total Mass of Algal Biomass: Calculate the overall weight of the algal biomass that was used for the extraction process. This includes both the oil and any other constituents found in the biomass. ( I have attached the formula as a PNG file. )

To determine the oil yield %, use the given formula after obtaining the mass of the extracted algal oil and the total mass of the algal biomass.
