Answer to Question #151472 in General Chemistry for NURUL AFIQAH BINTI MOHD HANAFI
Question #151472
A student prepares a solution by pipetting 15.0 ml of 0.50 M solution of trisodium phosphate (Na2PO4) into a 250 ml volumetric flask, adding deionized water precisely to the mark on the flask and mixing well. Calculate the molarity of Na2PO4 solution.
Expert's answer
To calculate the molarity of the solution we take the formula
"M_2 = (M_1\u00d7V_1) \u00f7 V_2\\newline M_2= (0.50\u00d715.0ml) \u00f7250ml\\newline M_2= 0.03M"
