Answer:
Number of moles = 2.1 mol
Explanation:
Given data:
Mass of molybdenum(vi) oxide = 300 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of molybdenum(vi) oxide = 143.94 g/mol
Number of moles = mass/ molar mass
Number of moles = 300 g/ 143.94 g/mol
Number of moles = 2.1 mol
