speed of diffusionI am having trouble understanding how to calculate speed of diffusion. The lab book states "multiply the length of time and the distance moved by 6 in order to calculate the speed of diffusion:______mm/hr." I do not understand how to do this calculation. The length of time I have is 10 mins and the distance moved is 9.2 m.
This may be a simple mathematical equation, but I have not been in school in _at_ 25 yrs, and it is boggling my old brain. Any help is appreciated
What is this multiply by 6? I maybe could understand 60 as that would change hours into minutes or whatever.
I don't if there is a special calculation for diffusion but I would just do this: 10 mins = 0.166 hr (10/60) 9.2m = 9200mm. so 9200/0.166 = 55,200 mm/hr. Anyone want to tell me im wrong. or right?
thanks. i didn't understand about the multiply by 6. the other execises used the same equation as you. i have a very inquisitvie mind and can't stand not knowing about something like this.
Easy but the explanation is bad. In fact what you are supposed to do is
1/(9200*6) and you get the good result. Why simply because you are in fact calculating: (1/6)*(1/9200) The first part of the equation is the conversion of time into hours 10 minutes= 1/6 of an hour Or multiply the time by 6, convert minutes in hour (yeah I know: 1 hour) and divide this by the distance multiplied by 6. Chris4 Explanation is probably better, but those completely stupid explanations fits with your text... HTH Patrick
