What is the percent composition by mass of hydrogen in H2SO4?

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?

Non renewable resources like petroleum eventually

Calculate the molarity of 48.0 ml of 6.00 m h2so4 diluted to 0.250 l .
