<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:
see explanation below
Explanation:
You miss the part of the temperature and pressure. According to what I found this is held under 30 °C (or 303 K) and 1 atm.
The problem states that we can treat this gas as an ideal gas, therefore, we can use the equation of an ideal gas which is:
PV = nRT (1)
Now, the density (d) is calculated as:
d = m/V (2)
We can rewrite (2) in function of mass of volume so:
m = d*V (3)
Now, the moles (n) of (1) can be calculated like this:
n = m /MM (4)
If we replace it in (1) and then, (3) into this we have the following:
PV = mRT/MM ----> replacing (3):
PV = dVRT/MM ----> V cancels out so finallly:
P = dRT/MM
d = P * MM / RT (5)
The molar mass of N2O is 44 g/mol So, replacing all the data we have:
d = 1 * 44 / 0.082 * 303
d = 1.77 g/L

<em>ANSWER:</em>
Objects that have the same charge, both positive or both negative, repel each other, and those with opposite charges attract each other. ... Similar to electric charges, opposite poles attract, and like poles repel. The stronger the magnets and the closer together they are, the stronger the magnetic force between them.
