What is the mass in grams of 2.30 x10^23 molecules of Fluorine

Chemistry
1 answer:
Jobisdone [24]3 years ago
8 0

Answer:

14.512g

Explanation:

Using the expression

mole = Number of molecules/6.022 x 10^23

mole of Fluorine = 2.30 x10^23/6.022 x 10^23

                             =  0.3819 mol

However,

mole = mass / molarmass

Mass of Fluorine = mole of Fluorine/ Molarmass of Fluorine

Molarmass of Fluorine = 18.998 x 2 = 37.996 g/mol

Mass of Fluorine = 0.3819mol/37.996g/mol

                              = 14.512g

How many moles are in 91.5 grams of Helium?
konstantin123 [22]

In order to find the number of moles with a given mass of Helium, we need to use its molar mass, which is 4.0026g/mol, therefore we will have:

4.0026g = 1 mol of Helium

91.5g = x moles of Helium

x = 22.86 moles of Helium in 91.5 grams

Electromagnetic waves with the shortest wavelengths and highest frequencies are called​
Feliz [49]

Gamma rays

Explanation:

Every member of the electromagnetic radiation has commensurate amount of energy, wavelength and frequencies.

The electromagnetic waves with the shortest wavelengths and the highest frequencies are the gamma rays.

  • Gamma rays also are the most energetic electromagnetic radiation.
  • The short wavelength of gamma rays suggests that more waves passes with times.
  • It's high frequency shows that a high amount of wave passes through a point at each passing of time.
  • These factors combines to give its high energy. Energy of an electromagnetic radiation is a factor of its wavelength and frequency.
  • Gamma rays are ionizing radiations which causes ionization of gas molecules.
