Question

2mg+o2=2mgo/calculate how much oxygen is required to combust 10 moles of magnesium from the given equation

Answer 1

Hello dear,

◆ Answer-
Amount of O2 required = 160 g

◆ Explaination-
# Given-
n(Mg) = 10 mol

# Solution-
According to reaction,
2Mg + O2 ---> 2MgO

To combust 2 mol of Mg, 1 mol of O2 is required.

Thus, to burn 10 mol of Mg, 5 mol of O2 is required.

Amount of O2 required,
Weight = Molecular mass × no of moles
Weight = 32 × 5
Weight = 160 g

Therefore, 160 g of O2 is required to burn 10 moles of magnesium.

Hope this helps you...
