Thank you for the opportunity to help you with your question!

First you need to find mass of the solution:

mass of solution is 500mL*1.28g/mL = 640 g

And now you can find mass of sulfuric acid in this solution:

mass of H2SO4 in this solution is: 640 g*0.381 = 243.84g

Please let me know if you need any clarification. I'm always happy to answer your questions.
