Question

How many moles of carbon dioxide are in 211 g of carbon dioxide?

Answer 1

Molecular mass of CO2 is 44.

Number of moles = given mass/molecular mass

Here, number of moles = 211/44 = 4.8 moles

Answer 2

Answer : The number of moles of carbon dioxide is 4.795 moles.

Solution : Given,

The mass of carbon dioxide = 211 g

The molar mass of carbon dioxide = 44 g/mole

The formula used :

$\text{ Moles of carbon dioxide }=\frac{\text{ Given mass of carbon dioxide}}{\text{ Molar mass of carbon dioxide}}$

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

The moles of carbon dioxide = $\frac{211g}{44g/mole}=4.795moles$

Therefore, the number of moles of carbon dioxide is 4.795 moles.
