    It's just applied maths. If you tried, I'm sure you'd fine it easy.
    If I tried - sure but it is just so dull

    The NaCl is initially 1 M (1 moldm^-3 -- concentration)

    If you dilute something 10 fold, you're making the volume 10x bigger, hence making the concentration 10 times smaller. So one 10-fold dilution leads to:

    \frac{1}{10} moldm^{-3} = 1\times10^{-1} moldm^{-3}

    If you were to 10 fold it again, you'd get a tenth of that:

    \frac{1}{100} moldm^{-3} = 1\times10^{-2} moldm^{-3}

    So on and so forth
    so will the answer be from start to end

    10^-1, 10^-2 , 10^-3 , 10^-4 ?

    i thought u start from 1 ?
