3
Mole measurement of the number of particles in a sample 1 mol He (g) = 6.02 x 10 23 atoms 1 mol CO 2(g) = 6.02 x 10 23 molecules

4
Molar Volume the volume of one mole of a gas at specified temperature and pressure SATP = 24.8 L/mol STP = 22.4 L/mol

5
Molar Volume Calculation use the formula:

6
Molar Volume Calculation use the formula: V=v/n

7
use the formula: Molar Volume Calculation V=v/n Molar Volume (L/mol)

8
use the formula: Molar Volume Calculation V=v/n Molar Volume (L/mol) Volume (L)

9
use the formula: Molar Volume Calculation V=v/n Molar Volume (L/mol) Volume (L) # of moles (mol)

10
Molar Volume Question What volume is occupied by 0.024 mol of carbon dioxide gas at SATP?

11
Assignment page 169-171 Do Everything

12
Molar Mass (M) the mass of one mole of a sample measured in grams per mole (g/mol) the identity of the substance DOES matter

13
Calculating Molar Mass (M) write the correct formula determine the number of each type of atom multiply the number of each type of atom by the atomic mass add up the products

14
Example Calculate the molar mass of Ca(NO 3 ) 2(s) M = 1 Ca + 2 N + 6 O = (140.08) + (214.01) + (616.00) = 164.10 g/mol

15
Mass - Mole Conversions use the molar mass of a substance to convert between mass and moles use the formula: n=m M

16
Mass - Mole Conversions use the molar mass of a substance to convert between mass and moles use the formula: n=m M # of moles (mol)

17
Mass - Mole Conversions use the molar mass of a substance to convert between mass and moles use the formula: n=m M # of moles (mol) mass (g)

18
Mass - Mole Conversions use the molar mass of a substance to convert between mass and moles use the formula: n=m M # of moles (mol) mass (g) molar mass (g/mol)

19
Example Calculate the mass of 2.3 moles of Ca(NO 3 ) 2(s) M = 1 Ca + 2 N + 6 O = (140.08) + (214.01) + (616.00) = 164.10 g/mol

20
Example n = m/M m= nM m= 2.3 moles x 164.10 g/mol m= 377.4 g
