The most appropriate answer is 'acetic acid contains a significant amount of carbon, but sodium hydroxide contains no carbon'. Organic compounds are those compounds that contains carbon atoms usually bonded to other elements such as oxygen, nitrogen and hydrogen. Organic compounds contain covalent single, double or even triple bonds.
Answer:
119.98 mL
Explanation:
Initial volume V1 = 123 ml
Initial temperature = T1 = 21◦C + 273 = 294 K
Initial pressure P1 = 760 Torr - 18.65 Torr = 741.35 Torr
Final volume V2= ???
Final temperature = T2= 21◦C + 273 = 294 K
Final pressure P2 = 760 Torr
From;
P1V1/T1= P2V2/T2
P1V1T2 = P2V2T1
V2 = P1V1T2/P2T1
V2= 741.35 * 123 * 294/760 * 294
V2 = 119.98 mL
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
