Using the equation below, how many liters of water can be made from 7.6 L of oxygen gas at STP?

V = 15.2 L

Explanation:

STP means that T = 273 K and P = 1 atm.

We use the PV=nRT equation to convert the given liters of oxygen to moles:

Now we convert O₂ moles to H₂O moles, using the stoichiometric coefficients of the equation:

Finally we use the PV=nRT equation once again to convert 0.68 moles of H₂O to liters:

i need mutiple choices

un recipient conține 6,4 moli de gaz. gazul hidrogen reprezintă 25% din totalul kilometrilor din container. în cazul în care presiunea totală este de 1.24 atm ceea ce este
