New Question What is the RELATIVE FORMULA MASS (R.F.M) of O_(2)(O=16) R.F.M.M=average of all elements=(16)/(2)=8 R.F.M.a=average of all elements= ((16times 2))/(2)=16 R.F.M.M=sum of all elements=16 R.F.M.M=sum of all elements=16times 2=

## Step 1:To find the relative formula mass (R.F.M) of , we need to sum the atomic masses of all the oxygen atoms in the molecule.## Step 2:The atomic mass of one oxygen atom (O) is given as 16.## Step 3:Since consists of two oxygen atoms, we multiply the atomic mass of oxygen by 2.### ## Step 4:Perform the multiplication to find the R.F.M.### #
