To solve this problem, we need to determine how many liters of carbon dioxide (
) are required to produce a given mass of sodium bicarbonate (
) at standard temperature and pressure (STP).### Step 1: Write the Balanced Chemical EquationThe balanced chemical equation for the reaction is:
### Step 2: Calculate Moles of
First, calculate the number of moles of
produced from the given mass.- Molar mass of
: - Na: 22.99 g/mol - H: 1.01 g/mol - C: 12.01 g/mol - O: 16.00 g/mol × 3 = 48.00 g/mol Total molar mass = 22.99 + 1.01 + 12.01 + 48.00 = 84.01 g/molGiven mass of
=
g = 200 gNumber of moles of
:
### Step 3: Use Stoichiometry to Find Moles of
From the balanced equation, the mole ratio of
to
is 1:1. Therefore, 2.38 moles of
require 2.38 moles of
.### Step 4: Convert Moles of
to Liters at STPAt standard temperature and pressure (STP), 1 mole of any gas occupies 22.4 liters.Volume of
needed:
Therefore, approximately 53.31 liters of carbon dioxide are needed to produce 200 grams of
at STP.
