When completing the diffusion of a dye through water, where does the 0 mm mark on your ruler go?
1 answer:
The Problem bother on the diffusion of substance
What is diffusion?
This can be defined as the movement of particles from a region of higher concentration to a region of lower concentration till equilibrium is reached
Explanation:
From the experiment seeks to measure the diffusion distance against time
Now when dye is dropped in water, the particles/molecules of the dye interacts with the molecules of water hence there is a mixtures which cause the dye to move from the initial position of higher concentration to lower concentration.
Hence the movement from the 0 mm mark increases in both directions

First we need to calculate the number of moles of FeS:
number of moles = mass (grams) / molecular mass (g/mol)
number of moles of FeS = 198.2/120 = 1.65 moles
From the chemical reaction we deduce that:
if 4 moles of FeS produces 8 moles of SO
then 1.65 moles of FeS produces X moles of SO
X = (1.65×8)/4 = 3.3 moles of SO
Now we can calculate the mass of SO:
mass (grams) = number of moles × molecular mass (grams/mole)
mass of SO = 3.3×64 = 211.2 g
