To find percent composition, you should first find the total of all of the components. Just add them all together:

100g+200g+50g=350g

Then, divide the amount of the component you are interested in, in this case, chocolate (50g), by the total amount to give:

\frac{50g}{350g}

This will give you the answer in decimal form, but to convert to a percent, you need to multiply by 100:

\frac{50g}{350g}*100

Therefore, the answer choice that is correct is A.

What did most of the particles that Rutherford shot at the gold foil do? What was the surprising behavior of a few of the partic
Masja [62]

Answer:

Explanation:

Rutherford gold experiment gave the explanation to some observations made on atoms.

When he shot the gold foil, most of the \alpha-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 \alpha-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 \alpha-particles, and more massive than the particles. Thus, he was able to determine the nucleus of an atom.
