Nba(oh)2 =mBa(OH)2/MBa(OH2)
-> mBa(OH2)= n.M
We have MBa(OH)2=171.32g/mol
nBa(OH)2= 9.45 mol
m = 171.32x9.45= 1618.974g

What is the molarity of a solution that is made by mixing 35.5 g of Ba(OH)2 in 325 ml of solution?

choli [55]

Answer:

$M=0.638M$

Explanation:

Hello!

In this case, since the molarity of a solution is calculated by diving the moles of solute by the volume of solution in liters, we first compute the moles of barium hydroxide in 35.5 g as shown below:

$n=35.5g Ba(OH)_2*\frac{1molBa(OH)_2}{171.34gBa(OH)_2}\\\\n=0.207mol$

Then, the liters of solution:

$V=325mL*\frac{1L}{1000mL} =0.325L$

Finally, the molarity turns out:

$M=\frac{0.207mol}{0.325L}\\\\M=0.638M$

Best regards!

PLEASE PLEASE HELP 1. Using a neutral atom that has an atomic number of 28 and a mass number of 152, how many protons, electrons

vampirchik [111]

Answer:

The answer to your question is:

Explanation:

Data

Atomic number = Z = 28

Mass number = A = 152

Atomic number number = # of protons

Mass number = # of protons + # of neutrons

Then

Protons = 28

Electrons = 28

Neutrons = 152 - 28 = 124
