Let us say that:
x = mass of 10% titanium alloy required
y = mass of 20% titanium alloy required
To solve this problem, we set-up two mass balances or
equations.
Overall mass balance: x
+ y = 100
x
= 100 – y ---> 1
Titanium mass balance: 0.10 x + 0.20 y = 0.17 (100)
0.10
x + 0.20 y = 17 ---> 2
Now we combine equations 1 and 2:
0.10 (100 – y) + 0.20 y = 17
10 – 0.10 y + 0.20 y = 17
0.10 y = 7
y = 70 g
Calculating for x using equation 1:
x = 100 – y
x = 100 – 70
x = 30 g
Answer:
x = 30 g of 10% titanium alloy required
y = 70 g <span>of 20% titanium alloy required</span>
Namely, what is 11.65 in percentage from 24.9
if we take 24.9 to be the 100%, let's see
![\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 24.9&100\\ 11.65&x \end{array}\implies \cfrac{24.9}{11.65}=\cfrac{100}{x}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccllll%7D%0Aamount%26%5C%25%5C%5C%0A%5Ctext%7B%5Ctextemdash%5Ctextemdash%5Ctextemdash%7D%26%5Ctext%7B%5Ctextemdash%5Ctextemdash%5Ctextemdash%7D%5C%5C%0A24.9%26100%5C%5C%0A11.65%26x%0A%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B24.9%7D%7B11.65%7D%3D%5Ccfrac%7B100%7D%7Bx%7D)
solve for "x".
