You want to compare a patient's measured calcium ion concentration to the normal calcium ion concentration in blood serum. The only range you can find is 4.5 - 5.5 mEq/L, but the blood results show a concentration of O.19 mmol/dL. Convert the measured calcium ion concentration from the blood results to mEq/L (to one decimal place).

An impure sample contains 1.01 g of impurities and 4.92 g of benzoic acid. The impure sample is dissolved in water, then heated. The solution is then cooled. How many grams of benzoic acid will recrystallize when the solution has cooled? Include the unit and two decimal places in your answer. The solubilities of the impurity and benzoic acid in hot water are found as an item in the Recrystallization Experiment folder. Solubility Data for Report Questions 10 Compound Cold Water solubility Hot Water Solubility Benzoic acid 0.42 g per 100 mL of water 5.79 g per 100 mL of water Impurity 0.61 g per 100 mL of water 4.62 g per 100 mL of water

Explain the results obtained in this experiment
scaling up Solutions Sometimes we know the concentration of a solute but we need to make a larger volume of the solution. Example: An IV saline solution is based on 0.9% NaCI = 0.9g/100mL (dL). To make 1L of the same concentration (0.9%), how many grams of NaCl would we need? Hint: first convert mL or dL to L. Next, to get from our original volume of 0.1 L to our desired volume of 1L, we need to multiply by a factor of 10. If we want to keep the concentration of this solution the same (0.9%) we will also need to multiply the amount of solute by the same factor of 10. Molar Ratios and Chemical Equations The concept of the mole is useful in chemical reactions. Molecules react in molar ratios which are expressed in equations. Neutralization of an Acid Example: HCI + NaOH → NaCI + H2O This equation says that 1 mole of acid is neutralized by 1 mole of base to produce 1 mole of salt and 1 mole of water. Since a mole is the MW in grams, then you can calculate how much base you need to to…
