Explain the meaning of solubility and compare the solubility of various substances.. Describe dilute, concentrated, saturated, unsaturated, and super-saturated solutions.. Relate changes in temperature and pressure to changes in solubility of solid and gaseous solutes.. Concentration. The amount of a specific substance in a known volume of solution. Concentrated Solutions. The amount of substance dissolved in solution is very high . It is difficult to dissolve more substance into solution. I can find percent change and find the relative error in linear and nonlinear measurements.. Percent Change. Expresses an amount of change as a percent of an original amount.. If a new amount is greater, the change is a . Example 1. Calculate the amount of each ingredient required for 1225mL of the formula listed below.. AT A GLANCE/. PHARMACY CALCULATIONS. FORMULATIONS. Ingredient. Master formula. Substance A. 175g. Substance B. AT A GLANCE/. PHARMACY CALCULATIONS. CONCENTRATED WATERS. 13. Concentrated Waters. Concentrated water is diluted to produce single- or double-strength water.. NB:. The pharmaceutical definition of concentrated water is one that is . Calculating the amount of substance needed in an initial concentration to produce a final desired dilution and volume. Example 1 What amount of a substance is required to make 1500mL of a product such that 50mL diluted to 1000mL will give a 1% v/v concentration? Calculating how much base to add to a product to achieve a lower desired concentration. Example 1 How much water should you add to 100mL of a 10% v/v solution to reduce it in strength to a 4% v/v solution? Example 1. How much chloroform is contained in 500mL of a 2% v/v concentration?. Method. Step 1: . A percentage is a fraction with a base of 100..  . Step 2: . By multiplication. *Remember, this is a . “Did you know . calculating . EMI can be so easy!”. . . What is an. EMI . means . a certain amount . to . be paid by the borrower to the lender for the predetermined period on a monthly basis. . Example 1. What amount of a substance is required to make 1500mL of a product such that 50mL diluted to 1000mL will give a 1% v/v concentration?. Method. Step 1: . Calculate the quantity of substance in the final dilution. MIXING CONCENTRATIONS. Calculating the strength of a mixture of two different concentrations.. Example 1. If you mix 100mL of a 5% v/v concentration of drug A with 200mL of a 20% v/v concentration of drug A, what will the final % strength be?. Matter is made of different kinds of particles. . We count the number of particles of that substance. . Since there are a very large number of particles in any substance, we need to define a unit of measure:.
