find the# of molecules in 5.3 moles of h20
To find the number of molecules in 5.3 moles of H2O, we need to use Avogadro's number, which is approximately 6.022 × 10^23 molecules per mole.
1 mole of any substance contains 6.022 × 10^23 molecules.
Therefore, if we have 5.3 moles of H2O, we can calculate the number of molecules by multiplying 5.3 by Avogadro's number:
Number of molecules = 5.3 moles × 6.022 × 10^23 molecules/mole
Calculating this value, we get:
Number of molecules = 3.19106 × 10^24 molecules
Thus, there are approximately 3.19106 × 10^24 molecules in 5.3 moles of H2O.
To find the number of molecules in 5.3 moles of H2O, you can use Avogadro's number, which states that there are 6.022 x 10^23 molecules in one mole of any substance.
First, determine the conversion factor between moles and molecules of H2O:
1 mole of H2O = 6.022 x 10^23 molecules of H2O
Now, multiply the number of moles of H2O by the conversion factor:
5.3 moles of H2O × (6.022 x 10^23 molecules of H2O / 1 mole of H2O)
To perform the calculation, multiply 5.3 by 6.022 x 10^23 and divide by 1:
Number of molecules of H2O = 5.3 × 6.022 x 10^23
Now, solve the equation:
Number of molecules of H2O = 3.19106 x 10^24 molecules
Therefore, there are approximately 3.19106 x 10^24 molecules in 5.3 moles of H2O.
