Find the wavelength of the electromagnetic radiation with a frequency of 3x10^-18Hz (Show Work)
aalyn [17]

Answer:

λ   = 1×10²⁶m

Explanation:

Given data:

Wavelength of radiation =  ?

Frequency of radiation = 3×10⁻¹⁸Hz

Solution:

Formula:

c = f × λ

c = speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s =   3×10⁻¹⁸Hz  × λ

λ  =  3×10⁸ m/s /  3×10⁻¹⁸s⁻¹

λ   = 1×10²⁶m

A chemist determines by measurements that 0.030 moles of nitrogen gas participate in a chemical reaction. calculate the mass of
zzz [600]
Remember that: 
number of moles = mass/molar mass

First, we get the molar mass of the nitrogen gas molecule:
It is known the the nitrogen gas is composed of two nitrogen atoms, each with molar mass 14 gm (from the periodic table)
Therefore, molar mass of nitrogen gas = 14 x 2 = 28 gm

Second we calculate the mass of the precipitate:
we have number of moles = 0.03 moles (given)
and molar mass = 28 gm (calculated)
Using the equation mentioned before,
mass = number of moles x molar mass = 0.03 x 28 = 0.84 gm
