    I understand concentration= number of moles/volume

    however this is the question i can't get

    Calculate the concentration of the following solutions in g dm-3
    (i will just put the first one as i am just looking for how to do it not for someone to do it for me )

    a) 0.01 mol dm-3 of HCl

    that is all the information i am given

    molar concentration (mol dm-3) = mass concentration (g dm-3)/RMM (g mol-1)

    that really makes no sense to me sorry

    Okay it's just a combination of the two formulae moles = mass/RMM and concentration = mol/vol

    If you work out the RMM of HCl and times it by the concentration in mol dm-3 you will get g dm-3

    okay so just to check would the answer be 0.01x 36.6=0.365?
