POSSIBLE POINTS: 2C_(7)H_(6)O_(2)+15O_(2)arrow 14CO_(2)+6H_(2)O Philly reacted 120g of Benzoic acid with a surplus of Oxygen gas.If the reaction produced 60g of Carbon dioxide what was Philly's percent yield? 50% 45% 78% 20%

Question

Answer 1

To calculate the percent yield, we use the formula:

### Step 1: Determine the molar mass of benzoic acid (

):

### Step 2: Calculate moles of benzoic acid reacted:

### Step 3: Use stoichiometry to find the theoretical yield of

:From the balanced equation:

2 moles of

produce 14 moles of

. Therefore, the mole ratio is:

Using this ratio:

### Step 4: Convert moles of

to grams:The molar mass of

is:

Theoretical mass of

:

### Step 5: Calculate the percent yield:The actual yield of

is given as 60 g. Using the percent yield formula:

Rounding to the nearest whole number:

### Final Answer:**20%**
