Chris has two tanks of helium gas. She wants to find out which tank has the most gas in it ,so she can blow up balloons for a party. Chris thinks that measuring the masses of the two tanks will identify which on contains the most gas. Will comparing the mass of the tanks help Chris know which one has the most gas in it? explain why or why not

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
