ChemistryWiki | RecentChanges | Preferences

1) How many grams of Carbon tetrachloride (C1Cl4, a great degreaser but also a suspect carcinogen) do I need to weigh out (massing) if I want 4.21 moles of this compound?

2) If I mass out 237g of Silicon dioxide (Si1O2, main ingredient in the mixture we call sand), how many moles do I have of this compound?

Answer: 1) 648g 2) 3.95moles
