The accepted value for the molar volume of a gas is 22.4 L. Sarah’s experimental data indicated that a mole of a gas had a volume of 19.6L. What was her percent error?

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%

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
