Answer:
32 feet
Step-by-step explanation:
Answer: 3 is 17.6471% of 17
Step-by-step explanation:
Column Resolution
Rs = 2[(tr)y - (tr)x]/[Wx + Wy]
= 2[17.63 - 16.4]/ [1.11 + 1.21] = 1.06
Average no. of plates in the column for substance x
N = 16(tr/ W)^2
N = 16(16.4/1.11)^2
N = 3490 plates
Average no. of plates in the column for substance y
N = 16(tr/ W)^2
N = 16(17.63/1.21)^2
N = 3397 plates
Plates Height
H = L/N
For substance x
H = 30/3490
H= 0.00916905 cm/plate
For substance y
H = 30/3397
H = 0.00883132 cm/plate
The student would get an 80%.
Since 5 is 20% of 25, subtract 20 from 100 and you get 80%
