convert the given mass of 4KNO3 into moles:
Mass of 4KNO3 = 4 * 101.1 g/mol = 404.4 g
Number of moles = mass / molar mass =
404.4 g / 101.1 g/mol = 4 moles
Finally, we can calculate the number of molecules using Avogadro's number:
Number of molecules = number of moles *
Avogadro's number
= 4 moles * (6.022 × 10^23 molecules/mol)
=2.4088 × 10^24 molecules
Therefore, there are approximately 2.4088 × 10^24 molecules in 4KNO3.
Mass of 4KNO3 = 4 * 101.1 g/mol = 404.4 g
Number of moles = mass / molar mass =
404.4 g / 101.1 g/mol = 4 moles
Finally, we can calculate the number of molecules using Avogadro's number:
Number of molecules = number of moles *
Avogadro's number
= 4 moles * (6.022 × 10^23 molecules/mol)
=2.4088 × 10^24 molecules
Therefore, there are approximately 2.4088 × 10^24 molecules in 4KNO3.
