WebThe empirical formula for glucose is CH 2 O and its relative formula mass is 180. Determine the molecular formula for glucose. (RAM: C=12, O=16, and H=1) Find the empirical formula mass = C (12) + H (2×1) + O (16) = 30 Divide the RFM by the empirical formula mass = 180 ÷ 30 = 6 WebFor an element, relative atomic mass is the average mass of the naturally occurring isotopes of that element relative to the mass of an atom of 12C. Which means one atom is given a relative atomic mass of exactly 12. … WebThe symbol for the relative formula mass is Mr and it refers to the total mass of the substance If the substance is molecular you can use the term relative molecular mass, but this term should not be used for ionic compounds such as sodium chloride parking at north shore hospital
