Each week before you have chemistry lab, someone needs to prepare all the solutions you will use in your experiment. Suppose your experiment for next week calls for 0.500 M NaOH solution, 3.00 M NH4Cl solution, and 0.100 M Na3PO4 solution. Calculate the mass in grams for each solute that would be needed to prepare 8.00 L of each of the solutions. Calculate the mass, in grams, of solute present in each of the following solutions: a. 225 g of...
