A chemist measured the amount of magnesium oxide produced during an experiment. She finds that 999. g of magnesium oxide is produced. Calculate the
number of moles of magnesium oxide produced.
Round your answer to 3 significant digits.

To find the number of moles produced, you need to multiply the mass (999 grams) by the molar mass of magnesium oxide. The molar mass is made up of the atomic weights of each element times their quantities in the molecule.

Molar Mass (MgO): 24.305 g/mol + 15.998 g/mol

Molar Mass (MgO): 40.303 g/mol

999 g MgO 1 mole
-------------------- x ---------------------- = 24.8 moles MgO
40.303 g
