n1 = cv = 0.1x0.25 = 0.025mol
n2 = cv = 0.5x0.3 = 0.15mol
so the total mole after mixing is;
0.025+0.15 = 0.175mole
and the total volume is;
250+300 = 550mL = 0.55L
thus the concentration is;
total mole/total volume = 0.175mol/0.55L = 0.32mol/L
hope that helps...
What is the concentration of the resulting solution when 250 mL of 0.1 M K3PO4 and 300 ml of 0.5 M K3PO4 are mixed?
