Question

Find the strength of one mole photon with a frequency of 2.5 × 10 ^ 14​

Answer 1

993.63 × 10² jmol    

Explanation:

Given: h = 6.626 × 10⁻³⁴ js, ν = 2.5 × 10¹⁴

Strength of one photon =hν

                                        = 6.626 × 10⁻³⁴ × 2.5 × 10¹⁴

                                        = 1.65 × 10⁻¹⁹

1 mole = Avogadro's number

Strength of one mole of photon = 1.65 × 10⁻¹⁹ × 6.022 × 10²³

                                                     = 993.63 × 10² jmol
