Answer:
1.09 M
Explanation:
Let's define the equation that will be used to calculate the final concentration of the resultant calcium nitrate solution. In order to calculate it, we need to find the total number of moles of calcium nitrate and divide by the total volume of the resultant solution:
![c=\frac{n}{V}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7Bn%7D%7BV%7D)
This equation firstly helps us find the number of moles of calcium nitrate. Multiplying molarity by volume will yield the moles. Adding the moles from the first component to the second component will provide us with the total number of moles of calcium nitrate:
![n_{Ca(NO_3)_2}=46.2 mL\cdot0.568 M+80.5 mL\cdot1.396 M=138.62 mmol](https://tex.z-dn.net/?f=n_%7BCa%28NO_3%29_2%7D%3D46.2%20mL%5Ccdot0.568%20M%2B80.5%20mL%5Ccdot1.396%20M%3D138.62%20mmol)
Now, the total volume of this solution can be found by adding the volume values of each component:
![V_total=46.2 mL+80.5 mL=126.7 mL](https://tex.z-dn.net/?f=V_total%3D46.2%20mL%2B80.5%20mL%3D126.7%20mL)
Finally, dividing the moles found by the total volume will yield the final molarity:
![c_{final}=\frac{138.62 mmol}{126.7 mL}= 1.09 M](https://tex.z-dn.net/?f=c_%7Bfinal%7D%3D%5Cfrac%7B138.62%20mmol%7D%7B126.7%20mL%7D%3D%201.09%20M)
Answer:
<h2>4.55 L</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is
![P_1V_1 = P_2V_2](https://tex.z-dn.net/?f=P_1V_1%20%3D%20P_2V_2)
Since we're finding the new volume
![V_2 = \frac{P_1V_1}{P_2} \\](https://tex.z-dn.net/?f=V_2%20%3D%20%20%5Cfrac%7BP_1V_1%7D%7BP_2%7D%20%20%5C%5C)
We have
![V_2 = \frac{195000 \times 3.5}{150000} = \frac{682500}{150000} \\ = 4.55](https://tex.z-dn.net/?f=V_2%20%3D%20%20%5Cfrac%7B195000%20%5Ctimes%203.5%7D%7B150000%7D%20%20%3D%20%20%5Cfrac%7B682500%7D%7B150000%7D%20%20%5C%5C%20%20%3D%204.55)
We have the final answer as
<h3>4.55 L</h3>

1.137448506 mol moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100.0 degrees Celsius.
<h3>What is an ideal gas equation?</h3>
The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas. The terms are: p = pressure, in pascals (Pa). V = volume, in
.
We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol:
PV= nRT
Given data:
P=100.0 kPa =0.986923 atm
T=100 degree celcius= 100 + 273 =373 K
V=35.5 L
Substituting the values in the equation.
n= ![\frac{\;0,98 \;atm \;X \;35,5 \;L }{\;0,082\;atm / \;K mol \;X \;373 K}](https://tex.z-dn.net/?f=%5Cfrac%7B%5C%3B0%2C98%20%5C%3Batm%20%5C%3BX%20%5C%3B35%2C5%20%5C%3BL%20%7D%7B%5C%3B0%2C082%5C%3Batm%20%2F%20%5C%3BK%20mol%20%5C%3BX%20%5C%3B373%20K%7D)
n= 1.137448506 mol
Hence, 1.137448506 mol moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100.0 degrees Celsius.
