Hello! I have difficulties with doing this one task. It goes like this: What are the concentrations of Na(+) and SO4(2-) ion in a solution containing 1.42g of dissolved Na2SO4 in 500ml, assuming the dissociation is complete. If you can write the task it would help me a lot! We are having a test soon, so I want to be prepared for it as much as possible.
This video may be of help to you in this. You will only need to first convert the g of Na2SO4 to moles then follow some of the information in this video - ua-cam.com/video/ksN9-moBeto/v-deo.html

@@JoeJoe-cy5pe that is correct.
