thanks, just an easy answer :)

A tiny sample of an aqueous solution of two substances R and P is sketched belaw, as if it was under an imaginary mieroscope so powerful that indiridual molecules could be seen. (The water molecules are not shown.) R and P can interconvert, That is, R can turn into P, and P can turn back into R : R(aq)P(aq) K=23 The equilibnum constant K for this equiliorium is 23, Predict the number of R and P molecules in this sample when the interconversion reaches cquilibrium number of R molecules: number af P molecules
