Answer: The mole allows people to calculate the number of middle schoolers entities (usually atoms or molecules. Isabella's number is an absolute number: there are 6.022 × 1023 middle schoolers entities is in 1 mole. This can also be written as 6.022 × 1023 mol-1.
Explanation: I hope that helped !!
<u>Answer:</u> The molarity of barium hydroxide solution is 0.118 M.
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction:
![n_1M_1V_1=n_2M_2V_2](https://tex.z-dn.net/?f=n_1M_1V_1%3Dn_2M_2V_2)
where,
are the n-factor, molarity and volume of acid which is ![HClO_4](https://tex.z-dn.net/?f=HClO_4)
are the n-factor, molarity and volume of base which is ![Ba(OH)_2](https://tex.z-dn.net/?f=Ba%28OH%29_2)
We are given:
![n_1=1\\M_1=0.102M\\V_1=24.0mL\\n_2=2\\M_2=?M\\V_2=10.3mL](https://tex.z-dn.net/?f=n_1%3D1%5C%5CM_1%3D0.102M%5C%5CV_1%3D24.0mL%5C%5Cn_2%3D2%5C%5CM_2%3D%3FM%5C%5CV_2%3D10.3mL)
Putting values in above equation, we get:
![1\times 0.102\times 24.0=2\times M_2\times 10.3\\\\M_2=0.118M](https://tex.z-dn.net/?f=1%5Ctimes%200.102%5Ctimes%2024.0%3D2%5Ctimes%20M_2%5Ctimes%2010.3%5C%5C%5C%5CM_2%3D0.118M)
Hence, the molarity of
solution will be 0.118 M.
