how many grams of sodium sulfate, Na2SO4, are produced from 34.3 g of sodium hydroxide, NaOH

Answer 1

There are two parts to the solution, which are finding a balanced equation, and using the equation to solve the question.

1) Balancing Equation:

Na_sSO₄ is made by combining Sodium Hydroxide (NaOH), and Sulfuric Acid (H₂SO₄), and so the balanced equation looks like this:

2NaOH + H₂SO₄ ———> Na₂SO₄ + 2H₂O

2) Doing actual calculations:

Since we are given grams, and end with grams, we need to do a couple of steps, that involve changing into moles, using a molar ratio to convert, and using molar mass to convert back into grams:

Grams of NaOH * NaOH Molar Mass Conversion * Molar Ratio * Na₂SO₄ Molar Mass Conversion

Here's the calculation:

34.3g NaOH * (1 mol NaOH/39.997 g NaOH) * (1mol Na₂SO₄/2 mol NaOH) * (142.04 g Na₂SO₄ / 1mol Na₂SO₄)

Calculating all that, we get 60.904 g Na₂SO₄
