Question 1 - 10
• What is the formula to convert from MOLES to GRAMS:
• Moles Grams
Answer 1 – 10
• # moles X (molar mass/1 mole) = mass (g)
Question 1 - 20
• What is the formula to convert from GRAMS to MOLES
• Grams moles
Answer 1 – 20
• Mass (g) X (1mole/molar mass) = # of moles
Question 1 - 30
• What is the mass of one mole of water?
Answer 1 – 30
• 18 grams!
• Work: 2(2) + 16 = 18 grams
Question 1 - 40
• How many moles of propane C3H8 are in 250.00g of propane?
