How many moles of chloroethylene contain 5.47×10^26 molecules?
There are 6.022E23 molecules in a mole of chloroethylene.
To calculate the number of moles of chloroethylene, we need to use Avogadro's number, which relates the number of particles (in this case, molecules) to the amount of substance (in this case, moles).
Avogadro's number (N_A) is approximately 6.022 × 10^23 molecules/mol.
The number of moles (n) can be calculated using the formula:
n = Number of molecules / Avogadro's number
Substituting the values:
n = (5.47 × 10^26 molecules) / (6.022 × 10^23 molecules/mol)
n = 9.085 moles (rounded to three decimal places)
Therefore, 5.47 × 10^26 molecules of chloroethylene contain approximately 9.085 moles.
To determine the number of moles of chloroethylene that contain a given number of molecules, we need to use Avogadro's number, which is approximately 6.022 × 10^23 molecules per mole.
First, we will convert the given number of molecules to moles using the following formula:
Number of moles = Number of molecules / Avogadro's number
Number of moles = 5.47 × 10^26 molecules / 6.022 × 10^23 molecules per mole
Number of moles ≈ 90.8 moles
Therefore, approximately 90.8 moles of chloroethylene contain 5.47 × 10^26 molecules.
