Question

Calculate mass of molecule of carbon dioxide (14co2)

Answer 1

The mass of one molecule of carbon dioxide is 12 + (2*16) = 12+32=44gm
14CO2 = 14*44 = 616 gm.

Answer 2

Answer : The mass of molecule of carbon dioxide $14CO_2$ is, 616 g/mole

Solution :

As we know that,

Molecular mass of carbon = 12 g/mole

Molecular mass of oxygen = 16 g/mole

Now we have top calculate the molecular mass of carbon dioxide.

$\text{Molecular mass of carbon dioxide}=14[\text{Molecular mass of carbon}+2(\text{Molecular mass of oxygen})]$

Now put all the given values in this expression, we get

$\text{Molecular mass of carbon dioxide}=14[12+2(16)]=616g/mole$

Therefore, the mass of molecule of carbon dioxide $14CO_2$ is, 616 g/mole
