How many grams of NaHCO3 would you need to react with 6 moles of H2SO4?
The balanced chemical equation is:
H2SO4(aq) + 2 NaHCO3 (s) —-> Na2SO4 (aq) + 2 CO2 (g) + 2 H2O

Answer:

[tex]\boxed{\text{1000 g}}[/tex]

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:                           84.01  

              H₂SO4 + 2NaHCO₃ ⟶ Na₂SO₄ + 2CO₂ + 2H₂O

n/mol:         6

1. Use the molar ratio of NaHCO₃ to calculate the moles of NaHCO₃.

[tex]\text{Moles of NaHCO$_{3}$ = 6 mol H$_{2}$SO$_{4}$} \times \dfrac{\text{2 mol NaHCO$_{3}$}}{\text{1 mol H$_{2}$SO$_{4}$}}\\=\text{12 mol NaHCO$_{3}$}[/tex]

2. Use the molar mass of NaHCO₃ to calculate the mass of NaHCO₃.

[tex]\text{Mass of NaHCO$_{3}$ = 12 mol NaHCO$_{3}$} \times \dfrac{\text{84.01 g NaHCO$_{3}$}}{\text{1 mol NaHCO$_{3}$}}\\\\= \text{1000 g NaHCO$_{3}$}[/tex]

You must use [tex]\boxed{\textbf{1000 g}}[/tex] of NaHCO₃.
