What is the molarity of a solution prepared by dissolving 8 grams of BaCl2 in enough water to make a 450. 0 mL solution? (Hint:
Salsk061 [2.6K]

Molarity is the molar concentration of the solute dissolved in a volume of a solution. The molarity of the solution prepared by dissolving barium chloride will be 0.085 M.

<h3>What is molarity?</h3>

Molarity is the ratio of the moles of the solute to that of the volume of the solution in Liters. It can be given as,

\rm Molarity = \dfrac{moles}{Volume}

Here, moles of the barium chloride can be given by the mass and the molar mass and volume is given as 0.450 L.

Substituting values in the equation:

\begin{aligned}\rm Molarity &= \rm \dfrac{mass}{Molar \;mass\times Volume}\\\\&= \dfrac{8}{208.23\times 0.450}\\\\&= 0.085\;\rm M\end{aligned}

Therefore, 0.085 M barium chloride is the molar concentration.

Find the length of time required for the total pressure in a system containing N2O5 at an initial pressure of 0.110 atm to rise
USPshnik [31]

Answer:

t = 37.1 s

Explanation:

The equation for the reaction is given as;

                  2 N2O5(g)  --> 4 NO2 + O2

Initial:          0.110                  -             -

change:        -2x                  +4x        +x

Final:          0.110 - 2x           +4x        +x

But final = 0.150atm;

0.110 - 2x    +  4x   +  x = 0.150 atm

3x = 0.150 - 0.110

x = 0.0133 atm

Pressure in reactant side;

0.110 - 2x

0.110 - 2 (0.0133) = 0.0834 atm

The integral rate law expression is given as;

ln ( [A] / [Ao] ) = -kt

k =  rate constant = 7.48*10^-3*s-1

ln (0.0834/0.11) = (7.48*10^-3)  t

upon solving, t = 37.1 s

Nitric oxide from car exhaust is a primary air pollutant. calculate the equilibrium constant for the reaction
Tema [17]

The equilibrium constant (Kp) for the formation of the air pollutant nitric oxide (NO) in an automobile engine at 530 degree C is 2.9 x 10 to the minus eleventh

N2(g) + O2 (g) = 2 NO (g)

A 4.75 Liter container is at a pressure of 120 kPa. What will its pressure be at a volume of 1.85L?
AlladinOne [14]

Answer:

The answer to your question is 308.1 kPa

Explanation:

Data

Volume 1 = V1 = 4.75 l

Pressure 1 = P1 = 120 kPa

Volume 2 = V2 = 1.85 l

Pressure 2 = ?

Process

To solve this problem use Boyle's law.

                 P1V1 = P2V2

- Solve for P2

                 P2 = P1V1 / V2

- Substitution

                 P2 = (120 x 4.75) / 1.85

-Simplification

                 P2 = 570 / 1.85

-Result

                  P2 = 308.1 kPa
