Answer: 4.86 x 10⁻³ mole.
Explanation:
The number of moles can be calculated using the relation; n = mass / molar mass. n is the number of moles, mass is the mass of the substance in g (m = 0.5 g), and molar mass of NaBr = 102.894 g/mole. n = mass / molar mass = (0.5 g) / (102.894 g/mole) = 4.86 x 10⁻³ mole.
