Answer:
x4,w = 0.03wt%
= 0.03/18 / 0.03/18 + 0.97/ 28.84
= 0.047mol%
Step-by-step explanation:
Let m1 = 100kg
Given:
m1 / m3 = 3.3kg
So, m3 = 3.3 x 100 = 30.30 kg
Degree of freedom analysis:
Xw,3 = 0.015 (18) / 0.015(18) + 0.985(28.84)
= 0.0094%wt
(1 – 0.01)(100kg) = (1- 0.001)m2
m2 = (1 – 0.01)(100kg) / 0.999
m2 = 99.1kg
(100kg)0.01 + 0.0094(30.3kg) = (99.1kg)0.001 + x4,w
(1-0.0094)(30.3) = m4 ( 1-x4,w)
m4 = 30.95kg
x4,w = 0.03wt%
= 0.03/18 / 0.03/18 + 0.97/ 28.84
= 0.047mol%

Step-by-step explanation:
x: adult tickets
t: children tickets
To find how much she can run in one minute we’re going to divide 800 by 5, to which we get 160.
She runs 160 meters in one minute.
We want to know how many meters she can run in 9 minutes.
160 * 9 = 1,440
She can run 1,440 meters in 9 minutes.
