<h2><u><em>When measuring data, the result often varies from the true value. Error can arise due to many different reasons that are often related to human error, but can also be due to estimations and limitations of devices used in measurement. Regardless, in cases such as these, it can be valuable to calculate the percentage error. The computation of percentage error involves the use of the absolute error, which is simply the difference between the observed and the true value.</em></u></h2>
Molarity can be defined as the number of moles of substance dissolved in 1 L of solution. In the given question , number of LiOH moles - 1.495 mol Dissolved volume - 750 mL molarity is calculated for 1 L = 1000 mL In 750 mL - 1.495 mol of LiOH is dissolved Therefore in 1000 mL - 1.495 mol / 750 mL x 1000 = 1.99 mol
