Determination of the new concentration of Dye and NaClO
A student has the following solutions available to them.
- Dye (1.23 x 10-6 mol L-1) – set to dispense in 1 mL aliquots.
- Deionised water – set to dispense in 0.5 mL aliquots
- NaClO (0.8 mol L-1) dispensed using a graduated pipette.
The student is assigned to Run 1. Calculate the initial concentration of dye and bleach in this run. Fill in only the blank part of the answer, to 2 significant figures.
Run 1
Dye (3.0mL)
Deionised water (1.0mL)
NaClO (0.50mL)
New concentration of Dye (mol L-1) = ___ x 10^-7
New concentration of NaClO (mol L-1) = ___ x 10^-2

New concentration of Dye (mol L-1) = 8.2 x 10^-7
New concentration of NaClO (mol L-1) = 8.88 x 10^-2
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
