To calculate the percentage purity of the aspirin sample, we can use the following formula:Percentage Purity =  Observed Melting Point / Literature Melting Point   100In this case, the observed melting point is 134.5C, and the literature melting point is 136C. Plugging these values into the formula, we get:Percentage Purity =  134.5 / 136   100Percentage Purity  98.9%Therefore, the purity of the aspirin sample is approximately 98.9%.
