Question

question 2
how many grams of sodium bicarbonate, nahco₃, are in 1.06 moles of sodium bicarbonate?
89.1 g nahco₃
101 g nahco₃
0.0521 g nahco₃
14.0 g nahco₃

Explanation:

Step1: Calcular masa molar de NaHCO₃

La masa molar de Na (22.99 g/mol) + H (1.01 g/mol) + C (12.01 g/mol) + 3O (3×16.00 g/mol) = 84.01 g/mol

Step2: Calcular masa en gramos

Masa = moles × masa molar = 1.06 moles × 84.01 g/mol = 89.0506 g ≈ 89.1 g

Answer:

89.1 g NaHCO₃
