What is the connection of ascorbic acid when one tablet is dissolved in 200cm cubed of water ?
BartSMP [9]

Answer:

              Option-D: 2.3 × 10⁻³ mol/dm³

Explanation:

Calculate moles of ascorbic acid,

Moles = Mass / M.Mass

Moles = 0.080 g / 176 g/mol

Moles = 0.00045 mole

Also,

Molarity = Moles / Vol. in dm³

Molarity = 0.00045 mol / 0.20 dm³

Molarity = 0.00227 mol.dm⁻¹ or 2.3 × 10⁻³ mol/dm³
