Question

Determine the number of moles of 300 g of Molybdenum (VI) oxide.

Answer 1

Number of moles = 2.1 mol

Step-by-step 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
