Answer
number of moles of Chlorine = 0.796 mol
Step-by-step explanation
Given:
Mass of Chlorine = 56.45 grams.
And knowing the molar mass of chlorine = 70.9 g/mol
Solution:
To calculate the moles we use the following equation:
n = m/M where n is the moles, m is the mass and M is the molar mass
n = 56.45g/70.9g/mol
n = 0.796 mol
