    Hey, having some trouble with my assessed homework.

    I think i've done this correct:

    a) 2dm3 of 0.05 M HCL, calculate the number of moles

    0.05 x 2 = 0.10 moles.

    but how would you do 25cm3 of 0.01 M NaOH? because the units are cm3.....

    and secondly, calculate the concentration of the following:
    a)i) 0.400 moles of HCL in 2.00 Litres of solution
    ii) cm3 of solution

    Thanks

    2 things to remember:

    1. To convert from  cm^3 to  dm^3 you divide by 1000
    2.  dm^3 is the same as a litre




    This should help you answer both of the questions
