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.
Normally, aspirin melts between 138 and 140 C. The melting point range for salicylic acid is 158 -160 C. At these temperatures, the crystals' lattice energy is broken, and they undergo a phase change from solid state to liquid state.ormally, aspirin melts between 138 and 140 C.
