What is the wavelength of electromagnetic radiation with a frequency of 9.23 × 107 Hz?

Igoryamba

Answer:

The wavelength of the given electromagnetic radiation is 3.25 m.

Explanation:

We know that,

Frequency (f) = c / λ;

where,

c - speed of light = $3\times10^{8} m/s$

λ - wavelength of the radiation.

Given,

f = $9.23 \times10^{7} Hz$ ,

From the above formula,

λ = $\frac{c}{f}$

λ = $\frac{3\times10^{8} }{9.23\times10^{7} }$

λ = 3.25m;

Therefore,

Wavelength of the given radiation = 3.25 m

How many moles of nh3 can he produced from the reaction of 38 g of n2

fiasKO [112]

N₂ + 3 H₂ → 2 NH₃

number of moles of N₂ = 38 g / 28 g/mol = 1.357 mol

1 mole of N₂ gives 2 moles of NH₃
1.357 mol of N₂ will give ?? mole NH₃

= 2 x 1.357 = 2.7 mol NH₃
