Question

how many cubic centimeters of concentrated nitric acid are needed to obtain a mass of 76g

a)14.2cm3
b)53.5cm3
c)76.0
d)107.9

Answer 1

Concentrated nitric acid has a density of about 1.4 g/cm 3 . The volume is the ratio of mass to
density: 76 g / 1.4 g·cm -3 = 54 cm 3 . The closest answer is b).
