Question

how can you calculate relative molecular mass and percentage composition of a compound ?

Answer 1

Answer:

Explanation:R.M.M=ADD ALL THE ATOMIC MASS OF ELEMENTS

FOR EXAMPLE R.M.M OF CO2=(12*1)+(16*2)=12+32=44

THERE IS NO UNIT FOR RELATIVE ATOMIC MASS

Answer 2

The Solution

• Step 1: Find the atomic mass of each element in the molecule. ...
• Step 2: Find the mass combination of each element. ...
• Step 3: Find the total molecular mass of the molecule. ...
• Step 4: Find the mass percent composition of each element.
