Answer:
21.182 g
Explanation:
There are about (6.0)(10^23) atoms in one mole of a substance, so the given sample has about 0.333 mol of Cu.
The atomic mass of Cu is 63.546 g/mol, meaning that the answer is about <u>21.182</u><u> </u><u>g</u>
Answer: Concentration of the dye in solution is 1.159 M
Explanation:
According to Beer-Lambert law, the absorbance is directly proportional to the concentration of an absorbing species.
Formula used :
where,
A = absorbance of solution = 1.657
C = concentration of solution = ?
l = length of the cell = 0.701 cm
= molar absorptivity of this solution =
Thus the concentration of the dye in solution is 1.159 M
I believe it's better for it to be more abundant because it's better to have more then less. Take water as an example. Water is an important factor to our survival and if we didn't have enough of that we would be in trouble. Or if we needed food but there wasn't enough more people would be dying from starvation. It's better to have a little more than a little less.
