주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Molarity

Molarity is a measure of concentration defined as the number of moles of solute per liter of solution. It is expressed in units of moles per liter (mol/L). To calculate molarity, one must know the amount of solute in grams, convert it to moles using the molar mass, and then divide by the volume of the solution in liters.

Molar Mass

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in a chemical formula. For compounds like Mn(NO3)2·2H2O, the molar mass is essential for converting grams of the compound into moles, which is necessary for molarity calculations.

Volume Conversion

Volume conversion is the process of changing the volume measurement from one unit to another, such as from milliliters (mL) to liters (L). Since molarity is defined in terms of liters, it is crucial to convert the volume of the solution to liters by dividing the volume in milliliters by 1000. This ensures accurate calculations of concentration.

Suppose that one wishes to use reverse osmosis to reduce the salt content of brackish water containing 0.22 M total salt concentration to a value of 0.01 M, thus render- ing it usable for human consumption. What is the mini- mum pressure that needs to be applied in the permeators (Figure 18.20) to achieve this goal, assuming that the oper- ation occurs at 298 K? (Hint: Refer to Section 13.5.)
