Question

how many grams of H2O are needed to react completely with 3.5 moles of ethylene?
I THINK that the reaction is a 1 to 1 mole reaction , so you should need 3.5 moles of H2O.

3.5 moles of H2O*(18.00g/1 mole)= mass of H2O

***2-significant figures.

Like I said, I think 3.5 moles of H2O is needed.
