How many grams of NaF form when 0.589 mol of HF react with excess Na2SiO3?

BartSMP [9]

Answer:

6.18 g

Explanation:

We know we will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

$M_r$ : 41.99

Na₂SiO₃ + 8HF ⟶ 2NaF + H₂SiF₆ + 3H₂O

<em>n</em>/mol: 0.58

1. Use the molar ratio of NaF:HF to calculate the moles of NaF.

$\text{Moles of NaF} = \text{0.589 mol HF} \times \frac{\text{2 mol NaF}}{\text{8 mol HF}} = \text{0.1472 mol NaF}$

2. Use the molar mass of NaF to calculate the mass of NaF.

$\text{Mass of NaF} = \text{0.1472 mol NaF} \times \frac{\text{41.99 g NaF}}{\text{1 mol NaF}} = \text{6.18 g NaF}$
