<u>Answer:</u> The energy of one photon of the given light is
<u>Explanation:</u>
To calculate the energy of one photon, we use Planck's equation, which is:
where,
= wavelength of light =
(Conversion factor:
)
h = Planck's constant =
c = speed of light =
Putting values in above equation, we get:
Hence, the energy of one photon of the given light is
Answer: m = 11.2 g C7H16
Explanation: First convert the mass of CO2 to moles. Then do the mole ratio between CO2 and C7H16 which is 7:1. Finally convert the moles of C7H16 to the mass of C7H16.
