Celery stalks that are immersed in fresh water for several hours become stiff. similar stalks left in a 0.15 m salt solution become limp. from this we can deduce that the fresh

You form water vapor by mixing oxygen and hydrogen at 730°c in a 5.4-liter container. this is the equation for the reaction: o2(g) + 2h2(g) → 2h2o(g). the partial pressure of oxygen before the reaction is 122.3 kilopascals, and there is excess hydrogen. how many moles of water are formed?
