Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Sally is a biochemist working in a biochemistry lab. For her experiments, she needs a stock solution of drug-A. The concentration of the stock solution needed is 100 milliMolar (mM). She needs to make 1.2 milliLiters (mL) solution of the drug-A. The drug is available in a salt form with a formula / molecular weight of 181.6 grams/mole. What is amount (quantity in grams) of drug-A will she have to weigh out to make the stock solution? (Formula weight and Molecular weight is the same thing).
You have been tasked with determining the wastewater solids generated by a community. To determine solids, you collect two effluent samples of 100 mL each. The first sample was placed, unfiltered, in a crucible and dried at 105 ̊C overnight. The weight of the dried sample and crucible was 5.6112 g, while the weight of the crucible was 5.6000 g. The second sample was filtered. The filter and drying dish were dried overnight at 105 ̊C after which they weighed 2.1085 g. The filter and drying dish were then placed in a muffle furnace at 550 ̊C for 30 mins, after which they weighed 2.103 g. The drying dish weighs 1.6000 g and the filter weighs 0.5 g. a) Determine the concentration of TS, TSS, VSS, FSS and TDS in mg/L: b) Does TSS concentration meet the federal effluent regulations? If not, what removal techniques would you recommend and what minimum percent must be removed prior to discharge?
In a lab experiment to study osmosis, you tied one end of a piece of dialysis tubing closed, added some pure water to the tubing, then tied the other end closed. The water-containing tubing was then rinsed, weighed (4.774g) and put into a beaker that contained sugar water. After about an hour, the tubing was removed from the beaker, rinsed and reweighed (4.316g). The determined masses are a. consistent with the expected osmosis that should have occurred b. not consistent with the expected osmosis that should have occurred; the tubing probably leaked c. not consistent with the expected osmosis that should have occurred; the tubing was probably put into pure water rather than sugar water d. not consistent with the expected osmosis that should have occurred; no cause is apparent e. no correct response
