Answer:
= 20.82 g of BaCl2
Explanation:
Given,
Volume = 200 mL
Molarity = 0.500 M
Therefore;
Moles = molarity × volume
= 0.2 L × 0.5 M
= 0.1 mole
But; molar mass of BaCl2 is 208.236 g/mole
Therefore; 0.1 mole of BaCl2 will be equivalent to;
= 208.236 g/mol x 0.1 mol
= 20.82 g
Therefore, the mass of BaCl2 in grams required is 20.82 g
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>
