Answer:
Percent error = 12.5%
Explanation:
In a measurement you can find percent error following the formula:
Percent error = |Measured value - Accepted Value| / Acepted value * 100
Based on the data of the problem, accepted value is 22.4L and the measured Value (Value of Sara) was 19.6L.
Replacing:
Percent error = |Measured value - Accepted Value| / Acepted value * 100
Percent error = |19.6L - 22.4L| / 22.4L * 100
Percent error = |-2.8L| / 22.4L * 100
Percent error = 2.8L / 22.4L * 100
Percent error = 12.5%
A substance cannot be a gas or a mixture. A pure<span> substance is something that occurs in nature. An element is made up of one type of atom only and cannot be split further. A compound has the combined properties of the elements from which it is made.

Explanation: }
<span>Iron phosphate when in an acid solution ionizes or dissociates into ions. The ions are the Iron (III) and the HPO4^2-. The net ionic equation should be as follows:
FePO4(s)+H3O +(aq)⇌Fe^3+(aq)+HPO4^2−(aq)+H2O(l)</span>
