It is possible for head lice to live temporarily on items such as bedding, couches, hair accessories, car seats, toys and clothing. Fortunately, head lice can only survive 24-48 hour off of the head and are relatively easy to remove from the home.
The molar mass of aspirin (2-acetoxybenzoic acid), C9H8O4, is 180.157 g/mol. The molar mass of aspirin (2-acetoxybenzoic acid), C9H8O4, is 180.157 g/mol.
The purity of the product will also be analyzed. The product will be analyzed by three different methods: melting point, titration, and spectroscopic assay. The melting point range of pure aspirin is 138-140 ï°C and the melting point range of the salicylic acid starting material is 158-161 ï°C.our instructor will demonstrate how to use the melting point apparatus. Allow the temperature of the melting point apparatus to increase 1 ï°C per minute starting from 120 ï°C. Measure the melting point range of the aspirin product.
