5.5 moles
2.0=x/2.75
2.0*2.75= x/2.75 (2.75)
5.5=x
Answer:
i think it's D tbh, just cus it was the scientist who did the work
Color is the answer Okie :3
Answer : The molar concentration of solution is 
Explanation :
Using Beer-Lambert's law :

where,
A = absorbance of solution = 0.614
C = molar concentration of solution = ?
l = path length = 1.0 cm
= molar absorptivity coefficient =
(assume)
Now put all the given values in the above formula, we get:


Therefore, the molar concentration of solution is
