Mass of Pd = 95.78 g which is close the the variant E) 95.89
Explanation:
To calculate the number of moles of palladium (Pd) we use the following formula:
number of moles = mass / atomic weight
mass = number of moles × atomic weight
mass of Pd = 0.90 × 106.42
mass of Pd = 95.78 g

Answer:
75.0%
Explanation:
Data obtained from the question. This includes the following:
Actual yield = 6.13g
Theoretical yield = 8.17g
Percentage yield =...?
The percentage yield can be obtain by using the following formula:
Percentage yield = Actual yield /Theoretical yield x 100
Percentage yield = 6.13/8.17 x 100
Percentage yield = 75.0%
Therefore, the percentage yield of water from the reaction above is 75.0%
M₁ x V₁ = M₂ x V₂
2.5 x V₁ = 0.50 x 100.0
2.5 x V₁= 50
V₁ = 50 / 2.5
V₁= 20 mL
hope this helps!
