(16.3 L) / (22.414 L/mol) x (4.0026 g He/mol) = 2.91 g
Answer:
90%
Explanation:
Percentage yield = ?
Theoretical yield = 50g
Actual yield = 45g
To calculate the percentage yield of a compound, we'll have to use the formula of percentage yield which is the ratio between the actual yield to theoretical multiplied by 100
Percentage yield = (actual yield / theoretical yield) × 100
Percentage yield = (45 / 50) × 100
Percentage yield = 0.9 × 100
Percentage yield = 90%
The percentage yield of the substance is 90%
All the elements in one group have the same number of valence electrons.
Because if the the technique is wrong the scientist is wrong I’m sorry it’s a bad answer :(
