How many moles of C2H2 are required to produce 0.70 mol of H2O?

0.70 moles of C₂H₂ are required to produced 0.70 moles of water

Explanation:

Given dа ta:

Moles of water produced = 0.70 mol

Moles of C₂H₂ required = ?

Solution:

Chemical equation:

C₂H₂ + O₂ → H₂O + CO₂

Balanced chemical equation:

2C₂H₂ + 5O₂ → 2H₂O + 4CO₂

Now we will compare the moles of water with C₂H₂.

H₂O : C₂H₂

2; 2

0.70 : 0.70

So 0.70 moles of C₂H₂ are required to produced 0.70 moles of water.
