How many moles of C2H2 are required to produce 0.60 mol of H2O? Express your answer to two significant figures and include the appropriate units.

0.60 moles

Explanation:

From the reaction:

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

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
