Question

Calculate the amount of magnesium that will react with 16.0 g of oxygen to produce 40.5 g of magnesium oxide.

​

Answer 1

24.3g

Step-by-step explanation:

Mr of Oxygen = 16 (15.999)

Mr of Magnesium = 24.3 (24.305)

Mass / Mr = moles

16.0g / 16 = 1

Mr x moles = Mass

24.3 x 1 = 24.3g
