Question -
Answer -
Mass percent of nitric acid in the sample = 69 % [Given]
Thus, 100 gof nitric acid contains 69 g of nitric acid by mass.
Molar mass of nitric acid (HNO3)
= {1 + 14 + 3(16)} g molтАУ1
= 1 + 14 +48
= 63 g molтАУ1
тИ┤ Number ofmoles in 69 g of HNO3
Volume of 100g of nitric acid solution
Concentration of nitric acid
тИ┤Concentrationof nitric acid = 15.44 mol/L
