For  the molarity and the  percentage of the mass of kcl are mathematically given as

%m/m = 23.1%, molarity  = 3.38M

<h3>What is the molarity?</h3>

Generally, the equation for the  percentage of the mass of kcl is mathematically given as

(mass of kcl/mass of solution)x 100

therefore

%m/m = (6.31/27.29)x100

%m/m = 23.1%

The molarity

(no of mol/ vol of sol)

molarity  = 0.0846mol/0.0250 L

molarity  = 3.38M

In conclusion, the molarity is given as

molarity  = 3.38M

Do constellations appear the same in Northern and Southern Hemisphere? Why or Why Not?
Mashcka [7]
The visible constellations<span> are definitely different between the Northern and Southern Hemispheres. In general, at any given point on Earth, only around 50% of the sky will be visible. We can understand this by considering the atmosphere as a sphere around the earth. The sky any person can view at one point can be compared to a giant dome equal to half of the sphere. And because the Earth rotates, the dome we can see changes, unless one is sitting directly on the North or South Pole.</span>
