how 2.5N H2SO4 prepared from concentrated H2SO4
You need 49,8 mL H2SO4 6,4M.
Remember M1V1=M2V2, where M is molarity and V is volume. M1/M2=V2/V1, 10/1=v2/v1, For diluting the acid, we can add acid to water. So, assuming that 10M H2SO4 is having 1ml of water, we should add 1M of H2So4 to 10ml of water.

Mix 120 g sulfuric acid with water to 1000 mL.
You need 252 g sulfuric acid.
Dilute 1M Tris 1:100
Molal is the number of mols of solute per kilo of solvent. Molar is the number of mols of solute per litre of solution. If you think those through, you should see that which is greater depends on the density of the solvent.
0.2% of anthrone was dissolved in 100ml of conc H2SO4.
