If 2.0 ml of concentrated h2so4 is diluted with distilled water to 250 ml in a volumetric flask, what is the resulting concentration in units of molarity and normality? what is the volume of the solution in (5) that should be diluted with distilled water to make a 0.025 n solution of sulfuric acid?

160 ml of water are needed to dilute the 2ml of to 0.025N

Explanation:

concentrated = 98% w/v = 1 M

2ml of concentrated have:

1M*0.002L =

When diluted to 250ml, the concentration becomes:

M=moles solute/volumen solution

N=(moles solute*#eq) /(volumen solution)

for the 0.025N solution

we take the same moles of =

then we find the volume:

N=(moles solute*#eq) /(volumen solution)

(volumen solution)=(moles solute*#eq) /N

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
