Answer:
Explanation:
given volume =5.3 litres
as we know that 1 litre =1 dm3
therefore 5.3 litres =5.3 dm3
now moles =given mass /molar mass
so mass =moles*molar mass
in order to find mass of carbon we need to find moles
therefore moles=given volume/standard volume standard volume at STP is 22.4 dm3
moles= 5.3/22.4
moles=0.236=0.24
now mass of carbon dioxide =moles*molar mass
mass = 0.24*44
mass=10.56kg
0.342 x ) photons are required to emit 1 joule of energy.
<h3>What is a photon?</h3>
A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy.
We need to find the number of photons emitted per second.
So we have E = hc ÷ λ
= (6.6 x x 3 x m/s) ÷ 6.78 x nm
= 2.92 x Joules
Now number of photons per second = I / E (I = intensity)
= 1 x joule / sec ÷ 2.92 x joule
= 0.342 x
Hence, 0.342 x ) photons are required to emit 1 joule of energy.
