Question:

Consider {eq}2H_2(g) + O_2(g) \to 2H_2O(g) {/eq}.

How many grams of oxygen are needed to produce 47.6 L of water at STP?

Moles to Grams:

Suppose the mass of a substance is m grams, and its molar mass is M grams per moles; we define the moles of the substance using the below equation.

{eq}n=\dfrac{m}{M} {/eq}

So, we determine a substance's mass using its molecular mass if the number of moles is given.
