Antique paintings will deteriorate more rapidly in a humid environment. Art museums will combat this by placing a desiccant into
the room to lower the moisture in the air. The chemicals used for this are strongly attracted to the water in the air, some so much that they actually pull enough water out of the air to form a solution. These are known as deliquescents. One common deliquescent is iron(III) chloride. A curator places a dish with 8.65x1023 formula units of iron(III) chloride into a museum storage room. This dish contains ___ grams of iron(III) chloride.
Although PPT was initially prepared from terephthalic acid (TPA) and 1,3-propanediol (PDO) in the 1950s, it has been mainly synthesized by transesterification of PDO with dimethyl terephthalate (DMT) similar to poly(ethylene terephthalate) (PET) and poly(butylene terephthalate) (PBT).
