a. Step 1: Determine the molar mass of
.- The molar mass of hydrogen (H) is approximately 1.01 g/mol.- The molar mass of oxygen (O) is approximately 16.00 g/mol.- Since there are 2 hydrogen atoms in
, the total molar mass of hydrogen in
is 2.02 g/mol.- The molar mass of
is 18.02 g/mol.b. Step 2: Calculate the percent composition of hydrogen in
.- The percent composition of hydrogen in
is calculated by dividing the total molar mass of hydrogen in
by the molar mass of
and multiplying by 100.- Percent composition of hydrogen in
= (2.02 g/mol / 18.02 g/mol) * 100 ≈ 11.19%Solution: The percent composition of hydrogen in
is approximately 11.19%.b. Step 2: Calculate the percent composition of oxygen in
.- The molar mass of carbon (C) is approximately 12.01 g/mol.- The molar mass of oxygen (O) is approximately 16.00 g/mol.- Since there are 2 oxygen atoms in
, the total molar mass of oxygen in
is 32.00 g/mol.- The molar mass of
is 44.01 g/mol.b. Step 2: Calculate the percent composition of oxygen in
.- The percent composition of oxygen in
is calculated by dividing the total molar mass of oxygen in
by the molar mass of
and multiplying by 100.- Percent composition of oxygen in
= (32.00 g/mol / 44.01 g/mol) * 100 ≈ 72.73%Solution: The percent composition of oxygen in
is approximately 72.73%.
