1.The concentration of the diluted solution determined in part b
and in part c must be equal. how do the values obtained compare?
explain
part b: preparation of a dilution solution
standard solution volume used: 10.00 mL
final volume of the solution: 25.00 mL
concentration of the standard solution:
0.800 mol/L
part c: experimental determination of the concentration of the
diluted solution
dough test tube with residue: 46.19g
dough test tube empty: 47.42g
volumen of solution used: 3.00mL or 0.003L
mass of the residue (solute):
47.42g - 46.19g= 1.3g
molarity of the diluted solution: 0.13mol/L
2. Describe the preparation of 250mL of a 0.006M Na2SO4
solution from the pure solid reagent.
3.If 25mL of 0.10M HCl is diluted to 500mL of solution, what
is the concentration of the resulting solution?
