the approximate no. of molecules of co2 present in 44g of co2 is:
mols CO2 = grams/molar mass
There are 6.02E23 molecules in 1 mol CO2.
6.022*10^23
To find the approximate number of molecules of CO2 present in 44g of CO2, you need to use the concept of the Avogadro constant and the molar mass of carbon dioxide.
The molar mass of CO2 is calculated as follows:
Molar mass of carbon (C) = 12.01 g/mol
Molar mass of oxygen (O) = 16.00 g/mol
Therefore, molar mass of CO2 = (12.01 g/mol + 16.00 g/mol + 16.00 g/mol) = 44.01 g/mol.
Now, you can use the following formula to calculate the number of molecules:
Number of moles = Mass / Molar mass
Number of molecules = Number of moles * Avogadro constant
First, calculate the number of moles:
Number of moles = 44g / 44.01 g/mol ≈ 1 mole (rounded to the nearest whole number).
Next, use Avogadro's constant:
Avogadro's constant = 6.022 x 10^23 molecules/mol (approximately).
Number of molecules = 1 mole * 6.022 x 10^23 molecules/mol
Number of molecules ≈ 6.022 x 10^23 molecules.
So, the approximate number of molecules of CO2 present in 44g of CO2 is approximately 6.022 x 10^23 molecules.
