Chap 10 Chemistry Test Study Concepts

1.     Convert grams of a molecule (CO2) to moles of CO2.   Practice with other molecular formulas.

2.     Convert moles of a formula to grams of a formula (Calcium Carbonate)

3.     Convert Liters of a  gas at STP to moles of the gas .  Ex N2 gas

4.     Convert grams of a gas at STP to liters of a gas at STP ex Hydrogen H2 gas

5.     Convert Liters of a gas at STP to mass  of the gas at STP  Ex H2O gas

6.     Find the # atoms of an element Ex H, in a certain amount  of moles of a molecular  formula  (C6H6)

7.     Balance an equation

8.     Find the percent composition  of each element in a compound given the formula of the compound

9.     Find the percent composition of each element given the mass of each element in the compound but not the formula

10. Find the empirical formula from example 9 (You have figured out percent composition already)

11.   Find the molecular formula  from # 10 (empirical figured out already  given the molecular mass

12. Given the empirical formula find the molecular formula given the molecular mass.
