Question

mass of mgo find and also amount of o2 when 480gm of mgo​

Answer 1

Answer:

800 gm

Explanation:

2Mg + O2 --- 2 MgO

no. of mols of Mg reacted is

mass/ molar mass

480/24 = 20 mols

by mol mol analysis

2 mol Mg form 2 mol MgO

1:1

20 mol Mg will form 20 mol MgO

mass of MgO = mol * molar mass

= 20 * (24+16)

= 800 gm
