The molecular formula of sucrose is - C₁₂H₂₂O₁₁
molecular mass of sucrose - 342 g/mol
molarity of sucrose solution is 0.758 M
In 1 L solution the number of sucrose moles are - 0.758 mol
Therefore in 1.55 L solution, sucrose moles are - 0.758 mol/L x 1.55 L
                                                                           = 1.17 mol
The mass of 1.17 mol of sucrose is - 1.17 mol x 342 g/mol = 4.00 x 10² g

Answer:
option D is correct
D. This solution is a good buffer.
Explanation:
TRIS (HOCH )
) CNH
CNH
if TRIS is react with HCL it will form salt 
 (HOCH )
) CNH
CNH + HCL ⇆   (HOCH
 + HCL ⇆   (HOCH )
) NH
NH CL
CL
Let the reference volume is 100
Mole of TRIS is =  100 × 0.2 = 20
Mole of HCL is =  100 × 0.1 = 10
In the reaction all of the HCL will Consumed,10 moles of the salt will form
and 10 mole of TRIS will left 
hence , Final product will be salt +TRIS(9 base)
H = Pk + log (base/ acid)
 + log (base/ acid)
8.3 + log(10/10)
8.3
