How many atoms would be found in a 2.1 mil sample of aipo4

What is the mass of 8 moles of sodium atoms

This drawing shows a human body system. what is the primary function of this body system?

Consider the reaction: n2(g) + o2(g) ⇄ 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
