Calculate the de Broglie wavelength of a shotgun

snow_lady [41]

Answer : The de Broglie wavelength will be $3.68\times 10^{-33}m$

Solution :

The formula used for de Broglie wavelength is:

$\lambda=\frac{h}{mv}$ ..........(1)

where,

$\lambda$ = wavelength = ?

h = Planck's constant = $6.626\times 10^{-34}Js$

m = mass = 1.2 g = 0.0012 kg

Conversion used : 1 kg = 1000 g

v = velocity = 150 m/s

Now put all the given values in equation 1, we get:

$\lambda=\frac{6.626\times 10^{-34}Js}{(0.0012kg)\times (150m/s)}$

$\lambda=3.68\times 10^{-33}m$

Therefore, the de Broglie wavelength will be $3.68\times 10^{-33}m$

The molar mass of barium nitrate (ba(no3)2) is 261.35 g/mol. what is the mass of 5.30 × 1022 formula units of ba(no3)2? 0.0900 g

liberstina [14]

Molar mass is the ratio of the mass to that amount of the substance. The mass of the barium nitrate in the formula unit is 23.0 grams.

The mass of a substance is the product of the molar mass of the compound and the number of moles of the compound.

Given,

Molar mass of barium nitrate = 261.35 g/mol

If, $6.022 \times 10^{23}$ have a mass of 261.35 g/mol then, $5.30 \times 10^{22}$ formula units will have a mass of,

$\begin{aligned}& = \dfrac{261.35 \times 5.30 \times 10^{22}}{6.022\times 10^{23}}\\\\&= 23.0\;\rm gm\end{aligned}$

Therefore, option C. 23.0 gm is the mass of barium nitrate.
