Help with this chemistry question please???
1 answer:
To find percent composition, you should first find the total of all of the components. Just add them all together:
Then, divide the amount of the component you are interested in, in this case, chocolate (50g), by the total amount to give:
This will give you the answer in decimal form, but to convert to a percent, you need to multiply by 100:
Therefore, the answer choice that is correct is A.

Explanation:
Rutherford gold experiment gave the explanation to some observations made on atoms.
When he shot the gold foil, most of the -particles passes through the foil undeflected nor absorbed. This faction of the particles propagated the foil as if there was nothing placed on their path.
The surprising behavior of a few of the -particles was that they were deflected from their initial path on hitting the gold foil.
This implies that there is a part of the gold foil which has the same charge as the -particles, and more massive than the particles. Thus, he was able to determine the nucleus of an atom.
