Answer:
3924
Step-by-step explanation:
what you have to do is see how many times sixteen goes into 6 first and since that is zero you look to the left so it is now 62. now you see how many times 16 goes into 62 which is 3 times and 16x3=48. Now you place ur 48 below ur 62 and subtract. u will get 14 obviously. now you carry down ur 7 and see how many times 16 goes into 147. Do this until u have no numbers left
In this item, we are going to use the concepts of total mass balance and component mass balance. We let the amount of the pure acid be equal to x.
Total mass balance:
7 + x = 7 + x
Hence, the total amount of the resulting solution is 7 + x
Component mass balance,
(1)(x) + (0.4)(7) = (0.7)(7 + x)
The value of x from the component mass balance is equal to 7.
