• Slides: 5 Mass to mole Conversions C. Molar Conversions molar mass 6. 02 1023 MASS NUMBER MOLES IN GRAMS OF PARTICLES (g/mol) (particles/mol) • The mass on the periodic table for each element is equal to 1 mole! • 1 mole of hydrogen = 1. 01 grams of hydrogen. • How many moles of carbon are in 12. 01 grams of carbon? 1 mole Carbon • How many moles are in 26 grams of carbon? 2. 16 moles Carbon • Now lets use dimensional analysis! To get the same answer! How many moles of carbon are in 26 g of carbon? -Underline the question. -Now predict what you think you need to solve the problem -Read the word problem -Are the important words circled? -Apply the steps to solve. Cancel out, perform operation -Verify your answer. Does it make sense? - Eliminate answers. (if multiple choice test) - Let the answer stay or rework the problem. (if test) 26 g C 1 mole C 12. 01 g C (molar mass) = 2. 16 moles C How many grams of water are in 2. 5 moles of water? -Underline the question. -Now predict what you think you need to solve the problem -Read the word problem -Are the important words circled? -Apply the steps to solve. Cancel out, perform operation -Verify your answer. Does it make sense? - Eliminate answers. (if multiple choice test) - Let the answer stay or rework the problem. (if test) 2. 5 mole.
