### 1.62 g
Explicación
## Step1: Determine the Molar Mass of Methane### Calculate the molar mass of methane (
) by summing the atomic masses of carbon (12.01 g/mol) and hydrogen (1.008 g/mol each for 4 hydrogens). The molar mass of
is
g/mol.## Step2: Calculate Moles of Methane Burned### Use the given mass of methane (0.59 g) to find the number of moles burned using the formula:
. Thus,
.## Step3: Use Stoichiometry to Find Moles of Carbon Dioxide Produced### According to the balanced equation, 1 mole of
produces 1 mole of
. Therefore, the moles of
produced are equal to the moles of
burned.## Step4: Calculate Mass of Carbon Dioxide Released### Calculate the mass of
using its molar mass (44.01 g/mol):
g/mol.## Step5: Round the Result### Round the calculated mass of
to the nearest 0.01 grams as required.
