Week 1 recap

• Grams to moles or moles to grams OF THE SAME SUBSTANCE, you use molar mass

  • when given Moles you Multiply, when given grams you divide

  • question/ problem contains only one substance ex. How many grams of NaCl are in 5 moles NaCl?

• converting moles reactant to moles product or vice versa, you use the mole ratio obtained from the coefficients. (front of mole foldable)

2 KClO3 ---> 2 KCl + 3 O2

How many moles of O2 can be produced by letting 12.00 moles of KClO3 react?

• Calculate the molar mass of KClO3

• Convert 12.00 moles of KClO3 to grams

• Calculate the molar mass of KCl

• How many moles are there in 96.92g of KCl?

Quiz review

Multiple Choice

If 12.00 moles of NaClO₃ react, how many moles of O₂ will be produced according to the reaction?

2 NaClO₃ → 2 NaCl + 3 O₂

• 12 moles of O₂

• 18 moles of O₂

• 9 moles of O₂

• 6 moles of O₂

Multiple Choice

Using the following equation:
Fe₂O₃(s) + 3H₂(g) → 2Fe(s) + 3H₂O(l)
How many moles of iron can be made from  6 moles H₂? 

• 4 moles Fe

• 6 moles Fe

• 9 moles Fe

• 2 moles Fe
