If I have 340 mL of a 0.5 M NaBr solution, what will the concentration be if I add

Answer:

Option C. 0.23 molar

Explanation:

The following data were obtained from the question given:

C1 = 0.5 M

V1 = 340mL

V2 = since 400mL was added to the original volume, therefore = 340 + 400 = 740mL

C2 =?

The concentration of the diluted solution can be calculated by using the following:

C1V1 = C2V2

0.5 x 340 = C2 x 740

Divide both side by 740

C2 = (0.5 x 340) / 740

C2 = 0.23M

Therefore, the new concentration of the solution is 0.23M

Divers who go to great depths in the ocean experience large differences in pressure between the surface and their final destinat
baherus [9]

Since solubility decreases rapidly as the diver returns to the surface, the risk of having “the bends” is greater as the diver returns to the surface.

The solubility of a gas refers to the amount of the gas that dissolves in a liquid. Solubility of a gas is dependent on pressure. The greater the pressure, the higher the solubility of the gas and vice versa.

Pressure increases with depth as a diver moves down the sea. More pressure is exerted, the deeper the diver goes. This means that solubility of nitrogen in blood increases at a greater depth.

As the diver returns to the surface, the pressure decreases rapidly and the solubility of nitrogen also decreases suddenly making the risk of “the bends” to be greater as the diver returns to the surface.

An object with a height of 0.3 meter is placed at a distance of 0.4 meter from a concave spherical mirror. An image with a heigh
Sophie [7]

We can use the magnification equation for this problem.

Magnification equation:

<em>hi/h0 = di/d0</em>

Where in <em>hi </em>: image size, <em>h0</em> : object size, <em>di </em>: image distance, <em>d0 </em>: object distance from mirror

So plugging in the given variables we will have the corresponding equation

0.1 m / 0.3 m = <em>di / </em>0.4 m

<em>di</em> = 0.1333333m

The generated image of the object is located 0.13 meters or 13 cm away from the mirror
