Answer:
3.78 x 10^24
Explanation:
I mol = 6.02X10^23 atoms
So,
I did not round the last number
the full answer was, 3.78056 x 10^24
It is B that one has the most mass
For this problem, we use the Beer Lambert's Law. Its usual equation is:
A = ∈LC
where
A is the absorbance
∈ is the molar absorptivity
L is the path length
C is the concentration of the sample solution
As you notice, we only have to find the absorbance. But since we are not given with the molar absorptivity, we will have to use the modified equation that relates % transmittance to absorbance:
A = 2 - log(%T)
A = 2 - log(27.3)
A = 0.5638
Answer:
Horizontal lines that represent different climate zones are called latitude.
Explanation:
Latitude is the distance that exists between a point on the Earth's surface to the equator, counted by the degrees of its meridian. That is, it is the distance, measured in degrees, that exists between any parallel and the line of the Equator. The latitude of a point is measured to the North or South of the zero parallel and its value can vary between 0 ° from the equator to 90 ° N from the North pole or 90 ° from the South pole.
Climate is related to latitude because it sets the amount of solar energy that a given region or place receives. Places located at high latitudes (far from the Ecuador) receive less sunlight than places located at low latitudes (near the Equator). Thus, cities distant from the equator and close to the poles have a cold climate, while at low altitudes there are high temperatures and a hot or tropical climate.
