Answer:
The answer to your question is 175 gallons
Explanation:
Data
60% antifreeze solution volume = ? = x
25% antifreeze solution volume = 25%
Final concentration 50%
Process
0.6x + 0.25(70) = 0.5(70 + x)
Simplification
0.6x + 17.5 = 35 + 0.5x
0.6x - 0.5x = 35 - 17.5
0.1x = 17.5
x = 17.5/0.1
Result
x = 175 gallons
Answer:
The water of crystallization of the intermediate analyte is 5.
Seeing as the question does not provide the value for weight of the salt on further heating (at 120° C), you can apply the steps in this explanation to attain that value.
Explanation:
XSO4.7H2O → XSO4 + 7H2O
8.1g 4.9g
8.1 - 4.9 = 3.9g of water evaporated
The ration of water to salt is:
XSO4 : H2O
grams : 4.9 3.2
moles: 72 + 32 + (16×2)=136 (1×2)+ 16= 18
0.036 0.178 (divide both sides by smallest value)
1 4.93
∴ <u>water of crystallization of intermediate is 5.</u>
