When 0.52 g of H2 and 0.19 g of I2 are confined to a 750.-mL reaction vessel and heated to 700. K... How come the volume of each is 0.750L. im confused is the total mixture 750ml or or each is 750ml because it says a reaction vessel so wont the total be 750ml? can somebody explain?

[Humza_Khan_2J]

The total rxn chamber is .750 L and the gasses both occupy this whole volume. This is why we use it as the volume to find the concentration of H2 and I2.

[Nicole Jacobs 1C]

the reaction vessel is 750 mL so use this to find the molarity of H2 and I2 to find moles per liter

[Katie Lam 1B]

Both gases are distributed throughout the 0.75 L container, so you use that volume for both H2 and I2.

[David Zhou 1L]

Gases spread to fill the entire container that they're housed in, unlike liquids and solids. So if the volume of the vessel they're in is .75 L, that's their volume.
