86.66 % by weight of ascorbic acid in the tablet, when 0. 1220 g vitamin c tablet was dissolved in acid. This required 11. 50 ml of 0. 01740 m to reach the endpoint.
A balanced chemical reaction is an equation that has equal numbers of each type of atom on both sides of the arrow.

So, the balanced chemical equation for the reaction will be:
→
That means, 3 mol of of ascorbic acid reacts with 1 mol of
Moles of available is 0.0174 X 0.0115 =0.0002001 mol
Moles of ascorbic acid to be yielded should be 3 X 0.0002001 =0.0006003
So, percent mass of ascorbic acid in the tablet will be:
(0.1057 / 0.1220) X 100 %
=86.66 %
Hence, the third option is the correct answer.

Answer:
0.0702J/g°C the specific heat capacity of the metal.
Explanation:m
where,
Q = heat absorbed by metal = 186.75 J
= Mass of metal= 19 g
= Initial temperature of metal =
=Final temperature of metal =
= specific heat of metal= ?
0.0702J/g°C the specific heat capacity of the metal.
