The equation for percent yield is
PercentYield= \frac{Actual}{Theoretical} X 100

As such, the theoretical yield or expected yield is, in this case, 122.7g of Pb, the actual in this case is 107.9g so we have
PercentYield= \frac{107.9}{122.7} X 100 \\ Percent Yield=0.879381X100 \\

Therefore, the percent yield of her reaction is 89.94%

Answer:

9.606 grams of citric acid are present in 125 mL of a 0.400 M citric acid solution.

Explanation:

Molarity : It is defined as the number of moles of solute present in one liter of solution.  Mathematically written as:

Molarity=\frac{\text{Moles of solute}}{\text{volume of solution in L}}

Moles of citric acid  = n

Volume of the citric acid  solution = 125 mL  =125 × 0.001 L= 0.125 L

(1 mL = 0.001L)

Molarity of the citric acid  solution = 0.400 M

0.400 M=\frac{n}{0.12 5L}

n  = 0.400 M × 0.125 L = 0.05 moles

Mass of 0.05 moles of citric acid :

0.05 mol\times 192.12 g/mol=9.606 g

9.606 grams of citric acid are present in 125 mL of a 0.400 M citric acid solution.

BigorU [14]

Mass of CO₂ = 132 g

<h3>Further explanation   </h3>

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

mole also can be formulated :

\tt n=\dfrac{mass}{MW}

moles of CO₂ = 3

mass of CO₂(MW=44.01 g/mol) :

\tt mass=mol\times MW\\\\mass=3\times 44.01\\\\mass=132.03~g\approx 132~g
