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:
It is known that relation between wavelength and frequency is as follows.
where, = wavelength
c = speed of light =
[/tex]\nu[/tex] = frequency
It is given that frequency is . Hence, putting this value into the above formula and calculate the wavelength as follows.
=
or, =
Thus, we can conclude that wavelength of given radiation is .
