Use stoichiometry to set up the calculations. First, you'll need to find the chemical equation, then the molar relationship between the components (ratio), then set up dimensional analysis to solve for the mass of the component needed to make the desired solution. For example, 100 mL of a solution that is 1M in sodium cation, using sodium chloride would need 5.844 g NaCl to produce M Na+ concentration. 1.) 100 mL of a solution that is 0.7 m in chloride...

Congratulations! You have just been hired as a researcher by the PRUB Chemical Company Because of the large number of people eating spicy foods (and often eating them too fast), this company has asked you to develop a new antacid. They have given you some information, but the rest you must discover for yourself. Your boss has suggested that aluminum hydroxide may be effective as an antacid. This...
