Answer:
The molarity of this solution is approximately .
Explanation:
The molarity of a substance gives its quantity (in number of moles) in each liter of the solution.
According to the question, there are of in each liter of this solution. The goal is to find the number of moles of formula units in that
contains three elements: Na, O, and H. Look up a modern periodic table for the relative atomic mass of each element:
- Na: 22.990.
- O: 15.999.
- H: 1.008.
Calculate the formula mass of .
.
That's the mass of each mole of formula units. Calculate the number of moles of formula units in that of
.
Apply the equation to find the molar concentration of this solution. In this equation, is the number of moles of the solute, and is the volume of the solution.
.
The answer is metal denting. I recommend formatting your question better
Answer:
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays. White light is apparently colorless light, for example ordinary daylight. It contains all the wavelengths of the visible spectrum at equal intensity.
