Determine the thickness, in mm, of a 7.0 cm* 3.5 cm of a piece of aluminum foil if it has a mass of 0.1260 g. Do you need anything else to answer this problem. If so, look it up.
volume=mass/density volume=length*breadth*thickness use these formulae
can you do that?
this is my first time doing this
can you guide me with the solutions
i will learn this way if you tell me and we dont start taking on here as it is very hard to do online
when you tell me i will follow your notes and whatever questions i have. I will ask my teacher at sschool
kk where are you from?
do you want the solution for that problem?
yes for this questionn
density of aluminium is2.7gm/cm3 volume=mass/density=0.1260/2.7=0.047cm3 volume=length*breadth*thickness=7.0*3.5*thickness=24.5*thickness =0.047 so thickness=0.047/24.5=0.002cm=0.02mm
is that a correct answer?
0.02 is answer
ohh you make it very easy
thank you
are you sure that is the anser
do you have any other easier solution than this
no
then that is the answer
what is the units
density of aluminium is2.7gm/cm3 volume=mass/density=0.1260/2.7=0.047cm3 volume=length*breadth*thickness=7.0*3.5*thickness=24.5*thickness =0.047 so thickness=0.047/24.5=0.002cm=0.02mm i have stated all the units in the solution
