    I'm not going to tell you the answer but say that 10ml is one hundredth of 1dm3 (1 Litre)
    To have 1 litre of a 1.0M solution you need 1 mole of whatever substance.
    So calculate how much 1 mole of NaCl weighs. Divide that number by the fraction of a litre that you need. The result of that is the answer in grams.

    N.B. Your answer should be somewhere between 1g and 0.3g

    Na - 23.0
    Cl – 35.5
    1 mole of NaCl weighs 58.5

    10ml = 1/100 of 1dm3

    58.5/100 = 0.585g Is that right? :emo:
