How many moles are contained in 1.20 x 1024 molecules CO2?
sd
To calculate the number of moles in 1.20 x 10^24 molecules of CO2, you need to use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole.
First, determine the number of moles by dividing the number of molecules by Avogadro's number:
Number of moles = Number of molecules / Avogadro's number
Plugging in the values:
Number of moles = 1.20 x 10^24 molecules / 6.022 x 10^23 molecules per mole
Simplifying the expression:
Number of moles ≈ (1.20 / 6.022) x (10^24 / 10^23)
≈ 0.199 x 10
≈ 1.99 moles
Therefore, there are approximately 1.99 moles of CO2 in 1.20 x 10^24 molecules.
To determine the number of moles in a given number of molecules, you need to use Avogadro's number, which is approximately 6.022 x 10^23. Avogadro's number represents the number of particles (atoms, molecules, or ions) in one mole of a substance.
To calculate the number of moles in 1.20 x 10^24 molecules of CO2, you can use the following formula:
Number of moles = Number of molecules / Avogadro's number
Let's substitute the given value into the formula:
Number of moles = 1.20 x 10^24 molecules / 6.022 x 10^23
Now, divide the numerator (1.20 x 10^24) by the denominator (6.022 x 10^23):
Number of moles = 1.20 x 10^24 / 6.022 x 10^23
Simplifying the expression, we get:
Number of moles ≈ 1.99 moles
Therefore, there are approximately 1.99 moles of CO2 in 1.20 x 10^24 molecules of CO2.
1 mol of anything is 6.02E23.
So 1.26E24/6.02
E23 = ?
