<u>Answer:</u> The concentration of Ba(OH)_2 comes out to be 0.129 M.

<u>Explanation:</u>

To calculate the concentration of base, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is H_2SO_4

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is Ba(OH)_2

We are given:

n_1=2\\M_1=0.1023M\\V_1=12.58mL\\n_2=2\\M_2=?M\\V_2=10.00mL

Putting values in above equation, we get:

2\times 0.1023\times 12.58=2\times M_2\times 10.00\\\\M_2=0.129M

Hence, the concentration of Ba(OH)_2 comes out to be 0.129 M.

Calculate the number of particles in a 0.75 gram sample of Calcium Nitrate; Ca(NO3)2​
kkurt [141]

The number of particles : 2.75 x 10²¹

<h3>Further explanation  </h3>

A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12  

1 mole = 6.02.10²³ particles  

\tt n=\dfrac{N}{N_o}

N = number of particles  

No = Avogadro number (6.02.10²³)  

n = number of moles  

While the number of moles can also be obtained by dividing the mass (in grams) with the molar mass of element or molecule  

0.75 gram sample of Calcium Nitrate; Ca(NO₃)₂

MW of Ca(NO₃)₂ : 164.09 g/mol

\tt mol~Ca(NO_3)_2=\dfrac{0.75}{164.09}=0.00457

The number of particles

\tt N=n\times N_o\\\\N=0.00457\times 6.02\times 10^{23}=2.75\times 10^{21}
