Mole = Mass / Molar mass
6.12 moles = Mass / 74.92 g/mol
Mass = 6.12 moles x 74.92 g/mol
Mass = 458.51g
6.50 x [10]^{2} will be the answer because you have to move the decimal to ex 6.50 instead of 00.650

<h3>
Answer:</h3>
2703 moles
<h3>
Explanation:</h3>
<u>We are given</u>;
- The equation for the reaction;
C₃H₈(g) + 5O₂ (g) → 3CO₂ (g) + 4H₂O (g)
- Moles of C₃H₈ are 901 moles
We are required to calculate the number of moles of CO₂ formed.
- From the equation, 1 mole of propane reacts with 5 moles of oxygen to form 3 moles of CO₂ and 4 moles of water.
- Therefore, the mole ratio of C₃H₈ to CO₂ is 1 : 3
Thus; moles of CO₂ = Moles of C₃H₈ × 3
= 901 moles × 3
= 2703 moles
Thus, moles of CO₂ formed will be 2703 moles
