How many grams of water will be produced if 4.6 moles of oxygen are consumed?

Hi there!

Stoichiometric coefficients are th' moles of reactants needed or th' moles of products formed in the reaction.

According to th' question :-

The balanced chemical equation for this synthesis reaction looks like this :-

2 H₂ + 2 O₂ —-—→ 2 H₂ O

∵ Th' reaction requires 2 moles of hydrogen gas and 1 mole of oxygen gas to produce 2 moles of water.

4.6 mol. O2 × 4 mol. of H2O × 18 g H2O

Divide th' above from :-
5 mol. O2 × 1 mol. H2O

The answer after calculations = 66 g

Hence,
66 g of water will be produced from 4. 6 moles of Oxygen.

~ Hope it helps!

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
