How many molecules are in 30 moles of NO3? Use the "^" symbol for the exponent (for example, 5.2 x 108 would be written as 5.2 x 10^8). Include the units in your answer.

How many significant figures should the answer have?

What is the answer with the correct number of significant figures and units?

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.
