You are at an estate sale and trying to decide whether to bid on a gold pendant that is said to be 24-carat (pure) gold. The pendant looks like gold, but you would like to check. You are permitted to make some measurements, and collect the following data: 

The pendant has a mass of 100 g in air and an apparent mass of 94.8 g when submerged in water. You know that the SG of 24-carat gold is 19.3, and the SG of 22-carat gold is 17.8; you decide to bid on anything that has SG > 19.0. Find the SG of the pendant, and decide whether you will bid.
