CHEM 111 Quiz: Mole-Mass Conversions.docx
Document Summary
The formula for carbon tetrachloride is ccl4 = 154 g/mol. 1 mole = 6. 02 x 1023 things = avogardo"s number: to convert grams ccl4 to atoms c: First multiply by moles ccl4 per gram ccl4. Then multiply by moles c per mole ccl4. Moles c cancel out: to convert molecules ccl4 to grams cl: grams cl. Then multiple by moles cl per mole ccl4. Then multiply by grams cl per mole cl. 1 mole = 6. 02 x 1023 things = avogadro"s number: to convert grams to molecules: molecule co = First multiply by moles co per gram co. grams co cancel out. Moles co cancel out: to convert molecules to grams: g co = 1. 04e+23 molecules co. Moles co cancel out: the formula for carbon dioxide is co2 = 44. 0 g/mol, to convert grams of co2 to grams of c: grams c = First multiply by moles of co2 per gram co2. Next multiply by moles c per mole co2.
