Answer:

The percentage yield is= 80%

Explanation:

% yield= actual yield/theoretical yield ×100

From The question

Actual yield= 240mg

Theoretical yield= 300mg

%yield= 240/300×100= 80%

What is the energy in joules of one photon of<br> microwaveradiation with a wavelength 0.122m?

pentagon [3]

<u>Answer:</u> The energy of photon is $162.93\times 10^{-26}J$

<u>Explanation:</u>

The relation between energy and wavelength of light is given by Planck's equation, which is:

$E=\frac{hc}{\lambda}$

where,

E = energy of the light = ?

h = Planck's constant = $6.626\times 10^{-34}Js$

c = speed of light = $3\times 10^8m/s$

$\lambda$ = wavelength of photon = 0.122 m

Putting values in above equation, we get:

$E=\frac{(6.626\times 10^{-34}Js)\times (3\times 10^8m/s)}{0.122m}\\\\E=162.93\times 10^{-26}J$

Hence, the energy of photon is $162.93\times 10^{-26}J$
