Answer:
3.26mole
Explanation:
Given parameters:
Mass of fluorine = 62g
Unknown:
Number of moles in one tube = ?
Solution:
A mole is the amount of substance that contains the avogadro's number of particles.
We can find the number of moles of a substance by;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of Fluorine = 19g/mol
Substitute in the equation:
Number of moles = [tex]\frac{62}{19}[/tex] = 3.26mole
