No, because RBC tells you the count of red cells in a standard volume of blood while HGB tells you the amount of hemoglobin in that blood, so they measure different things.

The ratio of HGB and RBC is called your MCH (mean corpuscular hemoglobin), so if you know two out of three of HGB, RBC, MCH then you can compute the third one.
HGB = RBC x MCH

RBC = HGB / MCH

MCH = HGB / RBC
