Calculate the number of moles of NaHCO₃ (sodium bicarbonate, or baking soda) in a 5.0 g sample of this substance.

Question

Quizplus · Accepted Answer

The molar mass of NaHCO3 is 84.01 g/mol.
Using the formula n = m/M, where n is the number of moles, m is the mass, and M is the molar mass, we get:
n = 5.0 g / 84.01 g/mol = 0.0595 mol ≈ 0.060 mol.
Therefore, the number of moles of NaHCO3 in a 5.0 g sample of the substance is 0.060 mole, which is best represented by choice B.
