Best ResponseYou've already chosen the best response.1For 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

Best ResponseYou've already chosen the best response.1For 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

Best ResponseYou've already chosen the best response.1ok :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?

Best ResponseYou've already chosen the best response.1Using 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

Best ResponseYou've already chosen the best response.0don't you divide or multipy the thing ?

Best ResponseYou've already chosen the best response.1yeah, density is mass divided by volume (g/mL)

Best ResponseYou've already chosen the best response.0what substances am I supposed to find the density of ?

CptnChiguire

Best ResponseYou've already chosen the best response.1All 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

Best ResponseYou've already chosen the best response.1That's what I got :) and you will also notice, that those are alse the values of the respective slopes in the graph ;)
