7 0

Answer:

52.0 gof CO2 contains 7.1 *10^23 molecules

1 molecule of CO2 has a mass of 7.3*10^-23 grams

Explanation:

Step 1: Data given

Mass of CO2 = 52.0 grams

Molar mass of CO2 = 44.01 g/mol

Number of Avogadro = 6.022 * 10^23 / mol

Step 2: Calculate moles of CO2

Moles CO2 = Mass CO2 / molar mass CO2

Moles CO2 = 52.0 grams / 44.01 g/mol

Moles CO2 = 1.18 moles

Step 3: Calculate molecules in 1.18 moles CO2

Number of molecules = 1.18 moles * 6.022*10^23 = 7.1 *10^23 molecules

1 molecule of CO2

Number of moles = 1 / 6.022*10^23

Number of moles = 1.66 *10^-24

Mass CO2 = 1.66*10^-24 moles * 44.01 g/mol

Mass CO2 = 7.3*10^-23 grams
