Question: What is the number of moles in 44 grams of CO2? (2021) 2021

Options:

Correct Answer: 1

Exam Year: 2021

Solution:

Molar mass of CO2 = 12 + 16*2 = 44 g/mol. Number of moles = mass/molar mass = 44g/44g/mol = 1 mole.

What is the number of moles in 44 grams of CO2? (2021) 2021

Step 1: Identify the chemical formula of carbon dioxide, which is CO2.
Step 2: Calculate the molar mass of CO2. Carbon (C) has a molar mass of 12 g/mol and oxygen (O) has a molar mass of 16 g/mol.
Step 3: Since there are 2 oxygen atoms in CO2, calculate the total mass of oxygen: 16 g/mol * 2 = 32 g/mol.
Step 4: Add the mass of carbon and the total mass of oxygen to find the molar mass of CO2: 12 g/mol + 32 g/mol = 44 g/mol.
Step 5: Use the formula for the number of moles, which is number of moles = mass / molar mass.
Step 6: Substitute the values into the formula: number of moles = 44 g / 44 g/mol.
Step 7: Calculate the number of moles: 44 g / 44 g/mol = 1 mole.
