The red lasers used to read the barcodes of products at the grocery stores produce light with a wavelength of 633 nm. The electrical power consumption of a single grocery store laser is 5.00000 × 10-3 J s-1. If the grid is burning CH4 gas (methane) to produce electricity, how many moles of CH4 must be burned to produce enough energy to run the grocery store laser for 365 days? The heat of combustion of methane is -890 kJ/mol. Assume the combustion energy is converted to electricity with 100% efficiency. (Hint, you will need to find the total amount of energy the laser emits as light, assuming the laser works with 100% effeciency i.e. all the electrical energy is converted to 633 nm light)
