Hey how can I do this chemistry question? I know you have to convert the g/dm-3

I k now you have to convert the g/dm-3 to mol/dm-3 but I don’t know exactly how!

Divide by the molecular mass of NaClO. Think about units; they help immensely.
Am I on the right track then?

I can’t read what you’ve written. If you divided the conc in gdm^-3 by the MM of NaClO, you’ll convert it to moldm^-3.
Do I convert the 100cm3 to 5cm3 and so convert the 4.5g to 0.9g?
Ad I use the concentration of the previous question the volume of it was 5cm3.
So do I do 4.5/0.1= 0.45g/dm3 and then do the answer / by the mr if NaClO
Or do I do 0.9/0.05= 18gdm3 then /the answer by the mr??

No. The answer to the previous question is given in moldm^-3, so how many grams of NaClO are there in 1dm^3 of bleach according to the label?

You can then convert the claimed concentration (in gdm^-3) to moldm^-3 by dividing by the Mr of NaClO
