Anyone?? please help! will give metal!
Is my math on this correct?
How many grams of magnesium oxide can be produced when 97.2 g Mg react with 88.5 g O2?
Unbalanced equation: Mg + O2 → MgO
Show, or explain, all of your work along with the final answer.
Balanced equation: 2Mg + O2 > 2MgO
Mass of Mg = 97.2g Mg
Molar mass of Mg = 24.3050g Mg
Mass of O2 = 88.5g O2
Molar mass of O2 = 32g O2
Mass of MgO = ?
Molar mass of MgO = 40.304g MgO
?g MgO = 97.2g Mg x (1mol Mg / 24.3050g Mg) x (2mol MgO / 2mol Mg) x (40.304g MgO / 1mol MgO)
=97.2 x 2 x 40.304 / 24.3050 / 2 = 161.2g MgO
Answer for first calculation = 161.2g MgO
?g MgO = 88.5g
