If 15.34 g of copper ii sulfate pentahydrate is dissolved to create 250.0 mL of solution what is the molarity of this solution? 

May 29th, 2015

250mL*(1L/1000mL)*{(x mole)}= 0.250

moles of copper ii sulphate, 0.25*x moles=0.250

=1 mole

now;

15.34*(1/249.685)=mol of copper ii sulphate

=0.06143 moles

liters of solution*molarity=moles

molarity=0.06143/0.25

=0.24572 M
