    The first three questtion you can read directly from the graph: a) 30 g b) 25 ml c) 45 g

    For question d: Density is how much mass there is per volume, that is, if you got X grams in Y mililitres, you have a density of X/Y g/ml

    For example, for 40 mL substance A I looked at how high the line was at the 40mL mark, and it seems it is 30g high

    ok :P now, see what I wrote before? Density is how much mass there is per volume, that is, if you got X grams in Y mililitres, you have a density of X/Y g/mL, are you following?

    Using the previous answers, for example for substance A we have there are 30g in 40 mL, therefore, it has a density of 30/40 g/mL

    (or three quarters grams per mililitre)

    don't you divide or multipy the thing ?

    yeah, density is mass divided by volume (g/mL)

    what substances am I supposed to find the density of ?

    All three of them :P I did for A, now you can do it for B and C, you just have to divide the respective masses and volumes

    That's what I got :) and you will also notice, that those are alse the values of the respective slopes in the graph ;)
