Question

if the atomic weight of carbon is 12 u then what will be the molecular weight of carbon dioxide​

Answer 1

Explanation:

If the atomic weight of carbon is 12 u

then, molecular weight of CO2

= 12×1 + 16×2

= 12 + 32

= 44 u

Answer 2

Answer:

⇒Molecular mass of Carbon Dioxide:

⇒Chemical formula:CO∨2

⇒This means carbon dioxide have 1 carbon and two oxygen.

So to find the molecular weight of Carbon Dioxide, we should multiply the atomic mass of the atoms with the number of atoms (of one type). Do the same with the other element and add both.

Numerical explanation of the above statement:

Atomic mass of carbon = 12u

Atomic mass of oxygen = 16u

( 1 × 12 ) + ( 2 × 16 )

= 12 + 32

= 44u

( u is unified mass)
