Answer:

Option (b) "inversely

"

Explanation:

The energy of a photon is given by :

E=\dfrac{hc}{\lambda}

Where

h is the Planck's constant

c is the speed of light

\lambda is the wavelength

Or it can be written as :

E=h\nu.....(1)

\nu is the frequency.

Equation (1) can be rearranged as :

h=\dfrac{E}{\nu}

So, it is clear that Planck's constant relates the energy in one photon of electromagnetic radiation is inversely proportional to the frequency of the radiation. Hence, the correct option is (b) "inversely".

How many grams are in 1.6 moles of potassium bromide?​
slava [35]

Answer:

190.4g

Explanation:

1.6mol of KBr (119.002g KBr/1 mol) = 190.4g

since you want to find grams, take the molar mass of KBr (119.002) per 1 mol and use it as your conversion factor (119.002g KBr/1 mol) which will then cancel out mols and leave you with grams.
