Answer:
![\text{ }1.25\times10^{23}\text{ formula units}](https://tex.z-dn.net/?f=%5Ctext%7B%20%7D1.25%5Ctimes10%5E%7B23%7D%5Ctext%7B%20formula%20units%7D)
Explanation:
Here, we want to calculate the number of formula units in the given molecule
We start by getting the number of moles
To get the number of moles, we have to divide the mass given by the molar mass
The molar mass is the mass per mole
The molar mass of calcium bromide is 200 g/mol
Thus, we have the number of moles as follows:
![\frac{41.5}{200}\text{ = 0.2075 mol}](https://tex.z-dn.net/?f=%5Cfrac%7B41.5%7D%7B200%7D%5Ctext%7B%20%3D%200.2075%20mol%7D)
The number of formula units in a mole is:
![1\text{ mole = 6.02 }\times10^{22}\text{ formula units}](https://tex.z-dn.net/?f=1%5Ctext%7B%20mole%20%3D%206.02%20%7D%5Ctimes10%5E%7B22%7D%5Ctext%7B%20formula%20units%7D)
The number of formula units in 0.2075 mole will be:
Answer:
0.384g/l
Explanation: the density version of the ideal gas law is pm=drt
in which p= pressure, m=molar mass,d=, density, r= to a constant which is 0.08206, and t=temperature so just input the values
PM=DRT. so to find d the formula would be D=RT\PM
D=<u>0.08206*242.5</u>
0.7311*70.90
D=0.384g/l
