Answer: 2,1,1
Explanation: (2)Na2HPO4=(1)Na4P2O7+(1)H20
Answer:
to simplify the number by using fewer digits
Explanation:
Answer:
1116g
Explanation:
We'll convert moles O2 -> moles of Na2O -> grams of Na2O.
Based on our balanced equation, we have 1 mole of O2 for every 2 moles of Na2O. This is our mole to mole ratio.
9 mol O2 x 
= 18 mol Na2O
We can convert mols -> grams using the molar mass of Na2O- 62g.
18 mol Na2O x 
= 1116g
