Better still... Search for: "58.44 g" and you'll get perfect results.
1 letter of context makes all the difference... and, as stated before, anyone who expects valid results from an otherwise arbitrary number is an idiot.
Google is not a mind reader (nor is any other inferior search engine, for that matter)... It works for non-arbitrary numbers (like Pi and e) because those numbers are exponentially more common. If the number of g/mol for salt suddenly became an extremely important number, so much so that it was required for every math/physics class from Middle School up, then guess what? It would suddenly start showing more results in searches. But it's not an extremely important number, so it's all going to end up moot.
Worthless article about a worthless project.
