a sample of sulphuric acid is 95.7% by mass and has a density of 1.84g/cubic cm.calculate the mass of pure H2SO4 in a 2.00L bottle and volume of acid that contain 200g of pure H2SO4.
1 cc has a mass of 1.84g.
2000 cc has a mass of 1.84*2000 = ?
How much is H2SO4? That's
1.84g/cc x 2000cc x 0.957 = about 3500 g (but you need to do it more accurately).
Then 2000cc x (200g/about3500g) = ? cc for 200 g pure H2SO4.
I need the answer please
