Answer:
1.26 g
Explanation:
Number of moles of ascorbic acid = concentration × volume
Concentration = 0.447 M
Volume = 16.00 mL
Number of moles = 0.447 × 16/1000
Number of moles = 7.152 × 10^-3 moles
Number of moles= mass/molar mass
Molar mass of ascorbic acid = 176.1 g/mol
Mass = 7.152 × 10^-3 moles × 176.1 g/mol
Mass = 1.26 g
