A chemical reaction in a lab experiment actually produces 1.23mol of BeBr2. The theoretical yield is 220g. To two decimal places
Mashutka [201]

Answer:

Percent yield = 94.62%

Explanation:

Given data:

Actual yield of BeBr₂ = 1.23 mol

Theoretical yield of BeBr₂ = 220 g

Percent yield = ?

Solution:

Theoretical yield in moles:

Number of moles = mass/molar mass

Number of moles = 220 g/168.82 g/mol

Number of moles = 1.30 mol

Percent yield:

Percent tiled = actual yield / theoretical yield × 100

by putting values,

Percent yield = 1.23 mol / 1.30 mol × 100

Percent yield = 0.9462 × 100

Percent yield = 94.62%

Practically: Add 1.66 ml of my 0.3M lemonade to a 15 ml microcentrifuge tube. Add 3.33 ml of your diluent (water, in this case)
Sedbober [7]

Answer:

We would need 10 mL of the concentrated CaCl₂ stock solution, and 30 mL of water.

Explanation:

To solve the question asked we can use the C₁V₁=C₂V₂ equation, where:

  • C₁ = 200 mM
  • V₁ = ?
  • C₂ = 50 mM
  • V₂ = 40 mL

We <u>solve for V₁</u>:

  • V₁ = 10 mL

We would need 10 mL of the concentrated CaCl₂ stock solution, and (40-10) 30 mL of water.
