Sucrose (C₁₂H₂₂O₁₁ ), which is commonly known as table sugar, reacts in dilute acid solutions to form two simpler sugars, glucose and fructose, both of which have the formula C₆H₁₂O₆. At 23 ^oC and in 0.5 M  HCl, the following data were obtained for the disappearance of sucrose:

Time  (min)	C12H22O11 (M)
0	0.316
39	0.274
80	0.238
140	0.190
210	0.146

Using the rate constant, calculate the concentration of sucrose at 140 min if the initial sucrose concentration were 0.316 M and the reaction were zero order in sucrose.
