Answer:
Number of moles = 0.01 mol
Explanation:
Given data:
Mass of sulfur trioxide = 0.762 g
Moles of sulfur trioxide = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of sulfur trioxide = 80 g/mol
Now we put the values in formula.
Number of moles = mass/ molar mass
Number of moles = 0.762 g / 80 g/mol
Number of moles = 0.01 mol
