How many grams of Na3PO4 will be needed to produce 425 mL of a solution that has a concentration of Na plus ions of 0.900 M?
Let us find moles first.
Molarity = moles of solute/Liters of solution ( 750 ml = 0.750 Liters )
0.375 M Na2SO4 = moles Na2SO4/0.750 Liters
= 0.28125 moles Na2SO4
===================
0.28125 moles Na2SO4 (142.05 grams/1 mole Na2SO4)
= 39.95 grams Na2SO4 needed
---------------------------------------you do significant figures!

How do you produce 1L of 10 percent ammonia solution from 25 percent ammonia solution?
To produce 1L of 10% ammonia solution from 25% ammonia solution, you need to dilute the 25% solution by adding a calculated amount of water. To do this, you can calculate the volume of the 25% solution needed and the volume of water needed using the formula: C1V1 = C2V2, where C1 is the initial concentration (25%), V1 is the initial volume, C2 is the final concentration (10%), and V2 is the final volume (1L).
