Part B
Use the formula C1V1 =C2V2
Where, C1 = initial concentration = 31.5 %
V1 = initial volume = 0.644 L = 644 ml
C2 = final concentration = 24.8 %
V2 = final volume = ?
C1V1 =C2V2 Thus,
V2 = C1V1 /C2
Substitute value in above equation
V2 = 31.5 644 / 24.8 = 818 ml
final volume = 818 ml
Part C
Use the formula C1V1 = C2V2
Where C1 = initial concentration = ?
V1 = initial volume = 510 ml
C2 = final concentration = 6.00M
V2 = final volume = 1.34 L = 1340 ml
Substitute the value in formula
C1V1 = C2V2
C1 = C2V2/V1
= 6.00 1340 / 510 = 15.76
C1 = 15.76 M
initial concentration of NaCl = 15.76 M
