Answer:
answer is 100/3 g
Explanation:
firstly compare the moles of the MgO produced with the moles of oxygen , you will get the mass of the required to react with the 6g of Mg
moles of O2 = moles of MgO
m / 32 = 10 ÷ (2 × 40 )
{ 2 is the stochiometric coeff. of MgO in the rnx i.e 2Mg + O2 = 2MgO }
mass of oxygen you get is 4g
now for the rxn of 6g Mg you require 4g of O2
and for the 50 g , the O2 require is 100/3g
