Since U is a universal set where S is its subset, then set U should consist of all the letters, numbers and punctuation mark in a keyboard. In other words, universal set U consists of the following elements:
U = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
U = (x| x comprised of all the letters in the alphabet fro a to z)
U = (!,.,,,?,!:,;,",',-)

Answer:
C4H10O + O2 = CO2 + H2O - Chemical Equation Balancer.
Step-by-step explanation:
Hi,
Let's say we need x mg from 1st compound, and y mg from 2nd compound.
0.20 × x + 0.40 × y = 40mg
0.30 × x + 0.20 × y = 30mg
0.20(x + 2y) = 40. => x + 2y = 200 => 2y=200-x
0.10(3x +2y) = 30. => 3x + 2y = 300
3x + (200 - x) = 300
2x = 100
x =50mg
50 + 2y = 200
2y = 150
y =75mg
