Question

For a tablet containing 500. mg of vitamin C, calculate how many ml of 0.095 M NaOH is required to reach the equivalence point.

Answer 1

mL of NaOH required =29.9mL

Step-by-step explanation:

Let us calculate the moles of vitamin C in the tablet:

The molar mass of Vitamin C is 176.14 g/mole

`moles=(mass)/(molarmass)=(500mg)/(176.14)=(0.5)/(176.14)=0.0028`

Thus we need same number of moles of NaOH to reach the equivalence point.

For NaOH solution:

`moles=MolarityXvolume=0.095Xvolume`

`0.00283=0.095Xvolume`

`volume=0.0299L=29.9mL`
