Answer:
15moles
Explanation:
Given parameters:
Mass of H₂SO₄ = 1469g
Unknown:
Number of moles = ?
Solution:
To solve this problem, let us first find the molar mass of the given compound;
molar mass = 2(1) + 32 + 4(16) = 98g/mol
So;
Number of moles = 
= 
Number of moles = 15moles
Answer:
11.25 moles of O₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
C₃H₈ + 5O₂ —> 3CO₂ + 4H₂O
From the balanced equation above,
1 mole of C₃H₈ reacted with 5 moles of O₂.
Finally, we shall determine the number of mole of O₂ needed to react with 2.25 moles of C₃H₈. This can be obtained as follow:
From the balanced equation above,
1 mole of C₃H₈ reacted with 5 moles of O₂.
Therefore, 2.25 moles of C₃H₈ will react with = 2.25 × 5 = 11.25 moles of O₂.
Thus, 11.25 moles of O₂ is needed for the reaction.
