what is the percentage concentration of a solution obtained by diluting a 98% sulfuric acid solution with an equal volume of water? (density of sulfuric acid = 1.83 g/cubic cm)

density by weight or volume?

Do you understand the question? Have you tried anything? Make it easy to help you.

Let the initial 98% solution be of 100g

#

So 98g h2so4

#

Density of water is 1g/cc

#

So we have 2/1 = 2cc water

#

If vol is doubled, we now have 4cc water aka 4g water

#

With still 98g h2so4

#

There w/w concentration is (98/102)*100
