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%
Answer:
3250 rubles.
Step-by-step explanation:
1 USD = 32.5 rubles so...
1 * 100 USD = 32.5 * 100 rubles.
The answer is 3250 rubles.
2 separate 7 ft boards = (2 * 7) = 14 feet
1 ft = 12 inches....so 14 feet = (14 * 12) = 168 inches
168/11 = 15.27 <== she has 15 eleven inch boards.
Answer:
1 =98
2 = 49
3 = 63
Step-by-step explanation:
Assuming 1 is at the center since it has the dot
<1 = arc 98
<1 = 98
We can find angle 2
<2 = 1/2 the intercepted arc
<2 = 1/2 (98)
<2 = 49
We can find angle 3
Angle formed by 2 chords
<3 = 1/2(arc 70 + arc56)
<3 = 1/2(70+56)
<3 =1/2 (126)
<3 = 63
Answer: The answer is D.
Step-by-step explanation: Given that the start does not have "- infinity" you only have "0" as a choice, and "0' is include n the answer I will go with the "[" (greater than or = to ".... Now for the fun one. the third month ends with 150... this is NOT LESS THAN 150 it is EQUAL TO 150 so three is NOT part of the answer....Hat is were the ") comes into play.
