Chapter 3: Q.21E (page 129)

Determine the mass in grams of each of the following:
(a) 0.600 mol of oxygen atoms
(b) 0.600 mol of oxygen molecules, O₂
(c) 0.600 mol of ozone molecules, O3

Short Answer

Expert verified

a) 9.6 g of O atoms

b) 19.2 g of O₂ molecules

c) 28.8 g of O₃molecules

Step by step solution

Determining the mass of 0.600 mol of oxygen atoms

0.600 mol of O atom

Molar mass = 16 g/mol

Number of moles = Mass/ Molar mass

0.600 = Mass / 16 g/mol

Mass = 0.600 x 16 = 9.6 g of O atoms

Determining the mass of 0.600 mol of oxygen molecules

0.600 mol of O₂ molecule

Molar mass = 16 x 2 = 32 g/mol

Number of moles = Mass/ Molar mass

0.600 = Mass / 32 g/mol

Mass = 0.600 x 32 = 19.2 g of O₂ molecules

Determining the mass of 0.600 mol of ozone molecules

0.600 mol of O₃ molecule

Molar mass = 16 x 3 = 48 g/mol

Number of moles = Mass/ Molar mass

0.600 = Mass / 48 g/mol

Mass = 0.600 x 48 = 28.8 g of O₃ molecules
