Simple Mole Concept Calculations Using Equations

Step 1––Analysis: This problem deals with particles (molecules) and moles––equation (2) fits this problem with n S being the unknown to be calculated. n S= p S N A Step 2––Variable Values: p S = 4.56 billion molecules = 4.56x109 molecules n S = x (to be calculated) N A = 6.022x1023 molecules/mol Step 3––Solution: x= 4.56¥109 ... ................
