At STP

1L O₂ → 2L CO₂
xL O₂ → 5.0L CO₂

x=2.5 L

If electromagnetic radiation has a frequency of 2.0×1015s−1, what is the radiation’s energy?(1 point)

Alika [10]

Frequency=v=2×10^15Hz
Energy=E

Using planks quantum theory

$\\ \sf\longmapsto E=hv$

$\\ \sf\longmapsto E=6.626\times 10^{-34}Js\times 2\times 10^{15}s^{-1}$

$\\ \sf\longmapsto E=13.252\times 10^{-19}J$

$\\ \sf\longmapsto E=1.3\times 10^{-18}J$
