After the extraction process, the organic solvent containing the organic compound was cooled and filtered after the crystals appeared. Upon filtration, the filter paper with the crystals are weighed immediately. Assume there were no additional steps in between and after, what are the possible errors committed in this set up?

Pls do fast within 5 minutes and i will give like for sure Solution must be in typed form To plan a liquid–liquid extraction we need to know the solute’s distribution ratio between the two phases. One approach is to carry out the extraction on a solution that contains a known amount of solute. After the extraction, we isolate the organic phase and allow it to evaporate, leaving behind the solute. In one such experiment, 1.235 g of a solute with a molar mass of 117.3 g/mol is dissolved in 10.00 mL of water. After extracting with 5.00 mL of toluene, 0.889 g of the solute is recovered in the organic phase. If we extract 20.00 mL of an aqueous solution that contains the solute using 10.00 mL of toluene, what is the extraction efficiency?
ADVANCED CHEMISTRY! RATE WILL BE GIVEN! PLEASE WRITE THE COMPLETE SOLUTIONS 1100 kg/h of a mixture containing equal parts by mass of methanol and water is distilled. Product streams leave the top and the bottom of the distilling column. The flow rate of the bottom stream is measured and found to be 710 kg/h, and the overhead stream is analyzed and found to contain 95.5 wt% methanol. Calculate the molar flow rates of methanol and water in the bottom product stream both in kmol/hour. Answers into 2 decimal places. Use 18 g/mol and 32 g/mol as the molecular weights of water and methanol respectively for the calculations

100 g of soil is leached with a strong solution of Calcium chloride such that all the exchange sites are occupied by Ca2+. The soil is subsequently leached again with a strong solution of magnesium chloride. It is determined that the resulting 100 mL leachate contains 5000 mg of Ca2+. What is the soil CEC (cmolc/kg)? The atomic wt. of Ca is 40 g/mol.please answer in word don't image upload thank you.
A tank with a capacity of 400 gal originally contains 150 gal of water with 25 lb of salt in solution.Water containing 2 lb of salt per gallon is entering at a rate of 10 gal/min,and the mixture is allowed to flow out of the tank at a rate of 5 gal/min. Find the amount of salt in the tank when overflowing starts
Given the following data, what is the molarity? Include the relative error Error is 1.0 mg or 1.0e-4
Amylum, commonly known as starch is a white powder with variable molecular formula due to the different number of repeating sugar units based on the plant that it is obtained from. A sample of amylum in the form of spherical beads was subjected to series of analyses to determine physicochemical properties in the quality control unit of a factory. From the results each bead is found to have a 4.5 mL volume and 1.47 g/mL density. 4 of the beads were placed in a reaction chamber combusted, as a result, 43.1 g CO2 and 14.7 g H2O were obtained. If the molecular weight of the amylum is 972.84 g/mol how many repeating units the starch molecule consist and what is the molecular formula of the starch?
