PLEASE HELP
How many grams of MgO can be produced with 4.63 grams of oxygen (O2)?

2Mg+O2=2MgO

11.6 grams of MgO can be produced with 4.63 grams of oxygen.

Explanation:

Mass of oxygen gas = 4.63 g

Moles of oxygen gas =

According to reaction,  1 mole of oxygen gas gives 2 moles of magnesium oxide, then 0.1447 moles of oxygen gas will giv e:

of magnesium oxide

Mass of 0.2894 moles of magnesium oxide:

= 0.29 mol × 40 g/mol = 11.6 g

11.6 grams of MgO can be produced with 4.63 grams of oxygen.

true

hope that

i believe that it is a exoplanet
