If you have 1.005 x 1024 molecules of Ca(OH)2 how many atoms do you have? Moles? Grams?

Over the last 90 years, scientists have added to the body of evidence supporting the big bang theory. what is the latest piece of evidence discovered in 2014?

How many grams of mgbr2 are needed to produce 75g or metal?
