Question

HOW to calculate molecular mass . Explain briefly step by step

Answer 1

Hello! dear,

Your answer goes like this ....

STEP:1:Determine the molecular formula of the molecule.
STEP:2:Use the periodic table to determine the atomic mass of each                             element in the molecule.
STEP:3:Multiply each element"s atomic mass by the number of atoms of                     that element in that molecule.This number is represented by the                      subscript next to the element symbol in the molecular formula.
STEP:4:Add these values together for each different atom in the molecule.

Thank you dear,

Hope It helps.
