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:
24
Step-by-step explanation:
A^2+b^2=c^2
In this case C^2 is solved and we have to solve for the remaining leg.
7^2+b^2=25^2
49+b^2=625
625-49=576
sqrt 576 = 24
The height is 24

0.3% = 0.003..." of " means multiply
0.003(200) = 0.6 <==
0.85% = 0.0085
0.0085(600) = 5.1 <==
what u can do to turn the percents to decimals is divide by 100.
0.3 / 100 = 0.003 and 0.85 / 100 = 0.0085
or u can move the decimal two spaces to the left
A mixed number is a whole number plus a fraction.
the smallest whole number is 1.
so no mixed number could be lees than 1.
mixed numbers that are 1/5 apart and are between 6 and 7
1-6/1 or 2-71
