Question

how much energy is contained in 1 mol of this

Answer 1

how do i do these

Answer 2

i know the pain of mastering chemistry lol.
But anyways you want to use Plank's Equation \[E=hv\] let \[v=\frac{ c }{ \lambda } \]

\[E=\frac{ hc }{ \lambda }\]
remember that h is a constant
c is the speed of light
and lambda is the wavelength
This allows you to solve for energy

ok thanks
