In other words, if we use 0.15 moles of NaCl and add water to make the final solution volume of 1.5 liters, we know that the molar concentration of the final solution will be 0.1 M NaCl as specificied in the problem statement.utting this info into the equation above we arrive at the following: 0.1 M NaCl = (moles of NaCl) / (1.5 L of solution). Multipy both sides of this relation by 1.5 to clear this number from the right hand side and we arrive at the answer: Moles of NaCl = 0.15 moles of NaCl required to make this solution.

Urine Drug Testing. Urine drug testing (UDT) is widely used for testing for opioids and illicit drugs. There are two types of UDT: a screening test and a confirmatory test. The screening test uses an immunoassay to look for the parent drug and/or metabolite. Most UDTs screen for marijuana, cocaine, opiates, PCP, amphetamines, while some also test for benzodiazepines and methadone.
