A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water.
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:
A compound
Explanation:
A compound is a pure substance that contains atoms of more than one element.
For example, water is a compound.
It is pure because it consists only of water molecules, and each molecule contains atoms of the elements hydrogen and oxygen.
1 mole C₆H₁₂O₆ ------------- 6 moles oxygen
3 moles <span>C₆H₁₂O₆ ----------- X
X = (3</span>×6)/1
<u>X = 18 moles</u>

I think it might be D or B
And my other two might be A or C
