Answer:
The right statement is "The percent transmittance of light, %T, will be higher for Sample 1 compared to Sample 2."
Explanation:
The Beer-Lambert Law states that the absorbance is directly proportional to the concentration of the substance.
Absorbance = εLc
ε: molar absorptivity coeficient
L: optical path length
c: molar concentration
Therefore, if ε and L are the same, the higher the concentration, the higher the absorbance and the lower the transmitance.
Since sample 1 has a higher concentration of CuSO₄ than sample 2, sample 1 has a higher absorbance and lower percent transmittance.
Weight/weight percentage is the percentage of mass of solute from the mass of the whole solution
w/w % = 32.7 %
this means that in a solution of 100 g - mass of KCl is 32.7 g
since solution is made of water and KCl
then the mass of water is - 100 - 32.7 = 67.3 g
therefore in 100 g of solution - 67.3 g of the solution is water
Since you're only asking for the last 3 items, here are the answers:
3. Maine is located in the northern hemisphere. If there is a high pressure, the wind is blowing clockwise. If there is a low pressure, the wind direction will be in the opposite direction.
4. Colorado is in the northern hemisphere. If there is a low pressure, the wind is going counterclockwise. If there is a high pressure, the opposite is true.
5. There is no map so I can't give you the exact answers.
