Answer:
12.5%.
Explanation:
The following data were obtained from the question:
Accepted value = 22.4 L
Experimental value = 19.6L
Percentage error =.?
Percentage error can be obtained by using the following formula:
Percentage error = |Experimental value – Actual value | / actual value × 100
Percentage error = |19.6 – 22.4|/22.4 × 100
Percentage error = 2.8 /22.4 × 100
Percentage error = 280/22.4
Percentage error = 12.5%
Therefore, the percentage error of Sarah is 12.5%
Answer:
667.105ml
Explanation:
V1VP1 / V2P2
V2=V1P1 / P2
Pressure at S.T.P is 760
V2= 600×845/760
V2=667.105ml
Therefore V2 = 667.105ml approximately
Honestly, you can look at the notes you took and even look down some things in google to help u solve ur answer
Actually it pretty much still is saturated with salt at the boiling point, which is just a tad over 100C. That's because the solubility curve for NaCl isn't much of curve. It's more of a nearly horizontal line.
Nonetheless, the solubility curve for NaCl does drift upward slightly as T increases, and so by the time the boiling point is reached, it won't be saturated.
