Complex conversions between units may require using what conversion factor

How many moles of gas are present if p=11 atm, v=12l, t=185k?

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

Does the number of ions in solution increase, decrease, or remain constant? it continuously decreases. it continuously increases. it decreases at first, then increases. it increases at first, then decreases.
