If a 0.75 mole sample of helium gas occupies a volume of 1.5 l, what volume will a 1.2 mole sample of gas occupy at the same temperature and pressure?

I hope it's correct :)

Is a logical series of steps

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
