Answer:
Some examples of homoatomic molecules are hydrogen gas, and oxygen gas and some examples of heteroatomic molecules are water, methane
Explanation:
<u>Answer:</u> The wavelength of an electron is
<u>Explanation:</u>
To calculate the wavelength of a particle, we use the equation given by De-Broglie's wavelength, which is:
where,
= De-Broglie's wavelength = ?
h = Planck's constant =
m = mass of electron =
v = velocity of electron =
Putting values in above equation, we get:
Hence, the wavelength of an electron is
Answer:
15.9 mol/kg is the molality for the solution
Explanation:
36.71% means that 36.71 g of solute are contained in 100g of solution
36.71 g → mass of solute
100 g → mass of solution (mass of solute + mass of solvent)
Mass of solvent → 100 g - 36.71 g = 63.29 g
Molality → moles of solute in 1kg of solent
We convert the mass of solute to mol → 36.71 g . 1mol/36.45 g =1.007 mol
We convert the mass of solvent from g to kg → 63.29 g . 1kg/1000g = 0.06329 kg
1.007 mol /0.06329 kg → molality → 15.9 m
Well you didnt give me enough information so i cant really answer your question
