CO has the largest formula mass.
Explanation:
The formula mass of carbon monoxide, CO.
The relative atomic mass of carbon is 12 and of oxygen is 16, so the relative formula mass is: 12 + 16 = 28
The formula mass of [tex]H_2O[/tex]:
[tex]\frac{(2\ H\ atoms) 1.01\ amu}{ 1\ H\ atom}[/tex] = 2.02 amu (1 O atoms)
(1 O atoms) 16.00 amu / 1 O atom = 16.00 amu
2.02 amu + 16.00 amu =18.02 amu
The formula mass of Ammonia, [tex]NH_3[/tex] is [14.0 g/mol + 3.0 g/mol] = 17.0 g/mol.
The formula mass of [tex]BeH_2[/tex] = 11.028062 g/mol
The formula mass is the multiple subscripts of each element in the formula and is given by the element of atomic weight that is given in each table. The formula mass is either U or Da (Dalton)
- The Co is carbon monoxide has a formula mass of 28.01 g/mole and is a colorless tasteless and odorless inflammable gas that is slightly less dense than the air. This gas has the highest formula mass. As carbon is 12 and oxygen is 16.
Thus the option C is correct.
