Answer:
The answer to your question is given below
Explanation:
To convert from Particles to grams, one must have a clear understanding of Avogadro's hypothesis. From the Avogadro's hypothesis, we can easily convert from mole to particles and to grams.
Avogadro's hypothesis gives us a background understanding that 1 mole of any substance contains 6.02x10^23 particles. With this in mind we can easily convert particles to grams and grams to particles.
Now consider the following example:
1. How many particles are there in 4g of carbon?
Solution:
From Avogadro's hypothesis, 1 mole of any substance contains 6.02x10^23 particles. This implies that 1 mole of carbon contains 6.02x10^23 particles.
1 mole of carbon = 12g
Now we can say that 12g of carbon contains 6.02x10^23 particles.
If 12g of carbon contains 6.02x10^23 particles,
then 4g of carbon will contain = (4x6.02x10^23) /12 = 2.01x10^23 particles.
The next example will teach us how to convert from particles to grams..
2. What mass of helium contains 4.2x10^24 particles.
Solution:
According to Avogadro's hypothesis,
1 mole of He contains 6.02x10^23 particles.
1 mole of He = 4g
We can thus, say that 4g of He contains 6.02x10^23 particles.
1f 4g of He contains 6.02x10^23 particles,
Then Xg of He contains 4.2x10^24 Particles i.e
Xg of He = (4x4.2x10^24)/(6.02x10^23)
Xg of He = 27.91g
Therefore, 27.91g of He contains 4.2x10^24 Particles
With the above illustrations I believe you have understood how to convert from grams to particles and from particles to grams.
