Answer:

0.60 moles

Step-by-step explanation:

From the reaction:

$2C_2H_2 + 5O_2 \to 4CO_2+2H_2O$

From above, Only 2 moles of CH2CH2 are required to produce 2 moles of water (H_2O).

As such, 0.6 moles of H2O will require:

x (CH2CH2) × 2 moles of (H_2O) = 0.6 moles (CH2CH2) × 2 mole of (H_2O)

x mole of (CH2CH2) = 0.60 moles

∴

0.6 moles of H2O will require 0.60 moles of CH2CH2
